It really is not that difficult. In my case, I have 4 styles that I use for most of my songs. Each style has one or two multistyles that essentially is the same as the 'parent' style but with different drum kits. For example, for my swings the main (parent) style is SWING. SWING has JazzTerryClarke^02-Brushes as the drums and two multistyles (substyles), SWING1 and SWING2. SWING1 is a copy of SWING with JazzTerryClarke^03-Ride,RideLd drums. SWING2 with JazzTerryClarke^04-CrStk,CrStTm.

Now SWING has 6 part markers defined as follows:
A/B - JazzTerryClarke^02-Brushes
C/D - JazzTerryClarke^03-Ride,RideLd
E/F - JazzTerryClarke^04-CrStk,CrStTm.

They can be used anywhere in the song. Of course, you can make any number of multistyles with the RD of your choice. If you are somewhat familiar with the StyleMaker, the process should take a matter of minutes.

If you have a lot of songs that uses the same style(s), it sure saves time over defining drum changes using Bar Settings. I've done similar styles for Bossa, 12/8 and Waltzes. That covers 99% of my songs. If you're wondering why I did this, it was mostly because I wanted some phrases to have a walking bass ('B' marker). Some drums go to the ride cymbal at the 'B' which I did not always want. In my swing examples, brushes are always A/B and sticks C/D. The E/F markers are used for special needs such as Bossa with percussion or Swing with CrackSticks.
