Saving Work from a Different Place?

Hello everyone. I am working on a script, and I have this game that has Saved Data, I want it to be able to be saved at other places as well, not the place that it is in. The script will explain.

--For LukeGabriel
game.Players.PlayerRemoving:connect(function(p)
if p:findFirstChild("leaderstats") then
p:SaveInstance("SavedStatPNum"..tostring(game.PlaceId),p.leaderstats)
end
end)
game.Players.PlayerAdded:connect(function(p)
for k = 1, 60, 0.03 do
wait()
if p:findFirstChild("leaderstats") and p.DataReady then break end
end
local Loaded = nil
if p:findFirstChild("leaderstats") and pcall(function() Loaded =  p:LoadInstance("SavedStatPNum"..tostring(game.PlaceId)) end) then
for j, v in pairs(Loaded:GetChildren()) do
pcall(function() p.leaderstats[v.Name].Value = v.Value end)
end
end
end)

I want the PlaceId to be the "Lobby" Game, not the game that a player is in. Any clues?

Thanks, LukeGabrieI
