I'm not sure if it is possible. Example:
1 | local player = game.Players.LocalPlayer |
2 | local TeleportService = game:GetService( "TeleportService" ) |
3 | TeleportService:Teleport( --[[placeid]] , player) -- I would try to make the default loading screen for this customized. |
Here's a tutorial on how to do it :
