Image chooser missing from Value in Setter (Property Trigger)

I want to change the Icon, when the button is checked. If I add a Property Trigger, and a Setter. Propery set to Icon, then select “Value”, there’s a dropdown for “Device Binding”, “Element Binding” and “Resource” but no dropdown for “Value” so I can choose an image from my list. I have to pre-select the name of the image I want to use before I drill down to this menu.

See attached.

That’s just a simple raw textbox on the Setter popup. Same goes for every property. It currently does not have filtering or drop down selections. You’ll have to manually enter the image or icon name.

Can drop-down selection and filtering be added? Seems a bit cumbersome to have to manually enter the name of an icon every time.
