I'm reworking my customizations to the command manager tabs and have decided to create an all-new sketch tab rather than modifying the default SolidWorks sketch tab. Every time they add a new button in a new release it screws up my customizations, so if I make an entirely separate sketch (and feature, assembly, etc.) tab, I don't have to worry about that anymore. 

So my question is, can I make SolidWorks recognize my new tab as the default tab? If I start a new sketch, I want SolidWorks to automatically switch to my new sketch tab rather than the old one. I can hide the old default tab, but SolidWorks won't see my new one as its replacement. Maybe there's a setting buried somewhere? Or in the registry? Same question goes for features, etc. Is this possible?
