I would like such option too. To bake the appearance violates the concept of building up geometry non destructive. 

Automated import of footnotes or endnotes is absolutely crucial in publishing.
I would welcome this feature in Affinity Publisher rather sooner than later!

ORIGINAL CONFUSION
"as it stands I have no idea what the "synchronize defaults from selection" actually does? the default style for a new object is just the last used style, and reverting just reverts styles back to the saved default, not this "temporary" one as expected.
"edit > defaults > save / revert" work as expected - but are not "temporary"
should there not be a "revert to temporary" as well as a "revert to saved" option? That would be a truly useful"
 
SOLVED & A SUGGESTION
I) Doesn't work as expected:
okay, my confusion is just that it doesn't work as expected. I assumed I could select an object, synchronise those as temporary defaults, continue designing and then at some point in the future click "revert" and the style that I had selected when I clicked "synchronise" would magically be applied. I assumed that this was simply a temporary version of the more permanent "edit > defaults > save / revert" - which works exactly that way - but the default is saved globally for all new documents. II) How it actually works:
How it actually works is that you need to "synchronize" before you start to draw your new object. Not afterwards. You can only revert the style of an object retrospectively to your globally saved defaults - "edit > defaults > save". Not to some other "temporary" style  To apply a different style, you must first select the object of the style you want to use, then click "synchronize". Now when you draw the new object that "synchronized" style will be applied. Otherwise, the style for new objects will always be whatever was last used for that object. III) How I would love for it to work
I would love for it to work as I had initially assumed. However, rather than leveraging the current "revert defaults" button to encompass "temporary" default overrides too, I would love there to be a "revert to temporary" button/option also. This would be scoped to the current document only, and would temporarily override the "saved" default for this document, until you click the "revert to defaults" - and then the defaults would once again return to your globally saved preferences.  That would add great consistency and also great functionality.  
I hope this also helps summarise things for anyone stumbling across this with the same confusion
 
thanks

For a while I have wondered why the corners tool doesn't have an option to scale with the object (it can get messy when scaling) and now with the recently added contour tool the same can be asked about it. If the corner tool can be overlooked the contour tool really feels like it should have the option since it's result is similar to an object's outline.
