Is it possible to bypass old copy/clone-tool scripts that are only creating client-specific builds?

(I'm aware that this is something I've asked about before, but the former suggestion hasn't worked)

Context: I'm trying to make a game that's a call back to the older build-and-fight games but with more basic building tools- including an old copy/clone tool.

Issue: The copy tool only seems to copy over blocks that only the builder can see. All other players are both unable to see or interact with the copied blocks- so it's not just a transparency issue.

And yes, I've attempted to move the code over to ScriptService and fire off a Remote Event (as with the numerous AlvinBlox suggestions)- but the Local Script has multiple parts which doesn't really mesh well with the gate example shown in the video content.

I've also tried finding other old clone/copy tools, but they all have the same issue. People can build with them, but they can't see anything that anyone else is making. And you can walk right through the builds that aren't yours- so again, it's not a problem regarding transparency.

Is there a way to bypass the client-sided issue in the tool's script without the numerous headaches above? Thanks.
