[Can you change stroke color for many polygons at once?]

Thanks for the replies, that solved it.
If Affinity is paying attention, changing primary UI based on selection state of the same thing should not change the UI. 

[Can you change stroke color for many polygons at once?]

I drew a bunch of hexagons in a row. When I select one I get access to its stroke properties, like color. When I select two I can't get access to color anymore. How do I change the stroke color of many polygons selected? See attached screenshots for clarification.
