I'm pretty sure you can't do what you're asking for.
The only way I could see close to that working would be if all regions were all in the same Swap Group, but it wont give you the behaviour of all the small regions swapping to region 2, and then whatever is in region 1 and region 2 switching at your convenience.
You can only have one Active region in a swap group, and that region is where your current active player for that swap group goes. They can't change swap groups. The swapping is only between a characters home region and the active region of that swap group, not home -> active (SG2) -> active (SG1).
