XY Background Image Reference

I can do a setup like this:
First column: [Image] --> select an Image.
Second column: [Drawing] --> With the initial value [Image]
That would be like:

Would that be possible also with “Background image for the XY coordinates” in the XY column type?
I tried it but it’s not working.
I even tried:

  • Select an image
  • Save the form
  • Edit the row

The XY column is still empty.

My goal is to use Different Background images depending on a previous selection.
Those images should be references to another table.
