Save brush settings without creating a new brush

Hey!

In my brush package, many brushes use the Rotation option for the angle jitter specified in the Shape Dynamics menu. I don't have a Wacom Art Pen that supports the Rotation function and I would like to change it to Tilt. I just want to change this setting and save it. I don't want to save it as a new brush, because then I would have to rearrange my entire brush pack layout. That would be too much time consuming just to change one setting. Also, I don't want to use the lock function as it then uses the titl for all brushes. (Not all brushes use the rotation feautre)

Is there no easy way to save to override the brush setting?

Thanks guys!
