Field label Change issue

Content

Hello,

I have to change labels for the Action + 'When...' fields for 'Change Manager' quick action.

I've tried doing this with Page Composer but as I checked it - it also changes the fields in 'Change Assignment' quick action.

I checked in the Manage Actions task and the actions (Change Manager and Change assignment) are in a separate action type.

Any ideas how to make the change only for the relevant action?

I am a bit concerned about using the User Interface Text.

Thanks
