Desync condition issue at high traffic with reserveservers

My system goes as follows:

Say Client 1. On Lobby 1. Requests for [Game Server 1] To be opened, But Client 2. on lobby 2. also requests for it to be opened very shortly after, Two servers are reserved for what is essentially the same server instance, and two players get sent to two different reserveservers, when ideally, all players should be sent to the first place reserved.

The only way I can think of to fix this is one global hander, or something like reserving the same server based on the same code, IE both clients could request server code “reserveserver1-3298312” and they would be teleported to the same reserve server, every time, But roblox’s reserve server doesn’t work like that, any tips?
