Accessing widgetui resources from xaml in wpfg

The game has two collections of resources, one in the widgetui folder for the old UI, and the other in wpfg for the new UI. Has anyone tried to reference a texture in widgetui in xaml?

For example, I tried things like

<Image x:Name="ImageBackground" Source="../../../widgetui/textures/backgrounds/history/wide_default_background.dds" />

and it doesn’t work.

I know that I could copy the old textures into wpfg resources. But if I subscribed another mod that modifies the old texture, my duplicated resources won’t be affected, causing inconsistency.
