How can I use this plugin to re size the Bradley's based on what bradley is spawned

It sounds like you are looking for a capability to basically auto resize entities of a given prefab. This plugin doesn't currently offer such capability, and I doubt it would make sense to add it since that could get out of control quickly. If you want to do that sort of thing, it could be accomplished pretty easily in a plugin that simply utilizes the API of Entity Scale Manager.

As for resizing bradley, vehicles and NPCs tend to not work very well when resized, so there might be some issues to watch out for.
