There is probably a thread about this already but I couldn't find it.
After you create a condition or action, it's impossible to change the selected data through the UI,
even if a condition or action is no longer valid because the selected data has gone missing.

Is there a particular reason for this restriction?
I understand that this is a fundamental part of how the condition or action works, but it's pretty annoying to have to create a new action or condition to change the selected data when business requirements have changed.
