How do tower defense games go about rigging?

I’m trying to find out how I would replicate the roblox rig template to my custom rig. Therefore copying all the m6ds and attachments to this empty rig of meshparts.

I’m planning on making a script but I was wondering if there was any plugins for this because I can’t imagine every tower defense game creates their own script to copy rigs onto a template. I would imagine something for this would’ve already been created.
