how could i put someone in the same place where they left the world

yea so um im running a pretty "budget" server and I came to a problem

I have 5 worlds (using multiverse-core and inventory)
world, world_nether, world_end, tnt and lobby

now people spawn in the lobby, they can click an NPC (citizens) to get transfered to the survival world (world) using /mvtp {player} world
I was wondering how I could make it so they get put to the last place they left "world" world from
(yea if this was bungeecord it would be easy as hell i assume, but it's not)

i tried thinking of solutions, but nothing came to mind

now this might be an idiotic question, or a case that's just not even solvable but I thought what's the worse that could happen if I ask yall
