How to change colour position w/o changing colour set

Hello all.
Let me start, saying, that I use Bambu Studio not in the same network segment as my P1S printer. I transport my projects by SD card.

With a downloaded 3mf from i.e. Makerworld, I import its colour settings in Bambu Studio. I.e. the model expects black PLA on AMS position 1 and white PLA on AMS position 2. Is there a simple way to tell the model, that my AMS has this on different positions?
Changing the colours, changes the look of the model, as it works with AMS offset.
I tried to edit the files inside the 3mf (i.e. filament id (slice_info.config) and/or filament_colour array (project_settings.config))
After all I surrendered and switched the spools in my AMS.
Any hint is welcome

You have to click on “Objects” to see the model color & number…you might have to click on the padlock to make your changes.
Click on color you want to change & it will bring up all the slots you have filled & you can choose what you want. Re-slice after, because sometimes it makes changes to multi-color prints that are not acceptable.
