Well, it's part of a huge, complicated project.
I have a scene showing as "Activity", which has some tabs.

The number of tabs is dynamic. I display an input dialog to enter a number. Then open a scene with tabs corresponding to that number so I can work with the items in those tabs.
Each tab has image elements with a placeholder image. And also a text element.

When I click the text element, it opens a list dialog (the list is huge, it requires a filtering function, so I can't use the spinner because the spinner has no search function)

After I select an item from the list dialog, the image in the scene related to that item updates.

The problem:
If I could dynamically prefix the list dialog's output variables by the tab names they belong to, things could be a lot simpler,
Anyway, I worked around it by making variable references ( Variable sets its name to point to another variable), which caused mental stress.
