In Apple Mail (under macOS Catalina, 10.15.3) there is a menu item "Move to Predicted Mailbox" . It already has a keyboard shortcut ^ CMD M.
I would like to change that to something else. Now, the problem is that this menu item changes every time I select a different message, depending on the folder Mail predicts. So, one time it is called 'Move to "MailboxA"' , another time it might be called 'Move to "MailboxB"' . Consequently, I cannot define a keyboard shortcut in System Preferences for it. I have tried to define it for "Move to Predicted Mailbox", but when Mail actually does predict a mailbox, then it shows the original shortcut, not mine.
Does anyone have an idea how I might be able to define a shortcut for this that "sticks"?
