Access state in nested repeating group

Hi there,
I am building a kanban board (see image). The elements are draggable.
Now I would like to filter the board by “workspaces”. I set up a custom state for the filtering but I can’t add the custom state in the constraints. I believe it is because I have a repeating group within a repeating group. I can see the state in the top layer repeating group. Is there any easy workaround for this?

Thanks a ton!

Doesn’t your filtering should occur in the data source of your RG? (which is on the same page than the filters so no issue)
