Also, you don't have to move the master layer on each spread individually.
You can select the master layer on one document page, right-click, and choose Edit Linked. Then you can use the menu item Layer > Arrange > Move to Front. Then click on the Finish button.
That will move the master layer to the top of the layer stack on all the spreads.
Of course, that is a one-time action, so if you draw anything on a page after that, you need to ensure it gets inserted below the master layer. Or you need to do that layer arrangement at the end of the project.
Also, in case it's not obvious, you can have multiple Master Pages applied to a single document page, so just put your "Draft" text on a separate Master, to facilitate this kind of layer arrangement.
I believe a logical way to do that would be to position the fill to the right or to the left (starting from the first node) for open shapes. Thus we'd have:
Closed shapes: Align stroke to Center, Inside, Outside.
Open shapes: Align stroke to Center, Left, Right.
