Rating scale/marker type: 'hover'. Changing my decision after mouse click

OS : Win10
PsychoPy version: v3.0.0
Standard Standalone? (y/n) If not then what?: y
**What are you trying to achieve?: That an answer (i.e. click on a category) is not logged in when I use ‘hover’ as marker type. In other words, I want to implement the possibility to reverse my last decision.

What specifically went wrong when you tried that?: I generated a rating scale with 12 answer possibilities (A, B, C…L). When I click on an answer (e.g. B) it is not possible to change my answer to e.g. F.

Is there a simple solution to this problem?

Thank you very much!
