A simple party switcher?

[AnthroMP]

Hello, I'm looking for a party switcher script. I've found many before, but they allow you to switch the main character (which I don't want). 

But they did have a "lock" feature, which I don't really know how to activate for certain characters.

But eh, I just need a script, thanks.

This script of mine can save/load parties as you wish.
