Edit default attributes and primary in ribbon

Hello

I'm adjusting the ribbon in microstation connect and would like to make my own attributes and primary groups, and not use the preset ones. The problem then is the shortcuts. Because in preferences - position mapping I have attributes & primary positions as default; A & S, but when I make my own Attributes and primary group they are treated just like any other group. That means that the shortcuts gets kind of messed up when I have/dont have those groups in different tabs. I want my own to be treated just like the attributes or primary group should be, but customize it myself. Is there a way to do this?
