How do you manage different key maps for character sets?

If you open Activate Maps, and look at both steps, it's easy enough to see how it's done. You could just add actions to turn on/off your custom key maps.

Yeah, it is easy but those actions are global. I need a way to activate Keymap1 and Keymap2 for character set 1. For character set 2 I need to activate Keymap3 and Keymap4.

You can specify which keymaps load initially for a character set but you can't toggle the keymaps in Activate Maps based on the character set. In other words, I want a way to toggle the keymaps that load with the character set.
