define chord symbols so that all imported chords use same interpretation

Currently moving a lot of Sibelius files to MuseScore. While every file requires some tweaking it overall works ok.

I am wondering, is there a way to have all chord symbols change to my preferred format?

What I mean by that is that for all minor chords I want to use the form X- and for all major chords I want to use X^.

So ideally instead of importing Abmaj7 I would automatically end up with Ab^7 after loading my saved style. But I don't understand how to tell MuseScore which format to use for which chord.

I found https://musescore.org/en/handbook/4/chord-symbols#change-appearance which seems to touch on what I am looking for. But I did not understand whether that documentation covers how to transfer existing chord symbols into my preferred form.

What I want to do is for an imported file to change all chords from the format I do not want to be using to the format I prefer:

Abmaj7 -> Ab^7
Abm7 -> Ab-7
Abm7b5 -> Abø7
...

Is this possible?
