Plugin to Avoid Region Select Size

Currently, ROBLOX has a max selection size of the “Region > Select” terrain tool of 512x512x512. I’m creating a large scale terrain map, and need to move one section to another that exceeds this size by 4-5 times.

Is it possible scripting wise to exceed this max selection limit and move this terrain either using the command line or a custom plugin, or is this an engine limitation that can’t be bypassed? Would there possibly be a workaround to select multiple 512x512x512 chunks together and move them as a grouped unit?
