TTT MapVote Cooldown

What do you guys think would be the smartest way to implement a change map cooldown to TTT?

Currently, the server uses MapVote, which is that GUI voting addon that lets users vote for a map.

I’d like to make a map unvotable for 5 rounds.

How should I go about this? Should I store the maps as Pdata? Or what?

I can’t really figure this out because every time the map changes, the code will be reloaded and any tables be cleared.

If you are talking about the fretta style mapvote by Willox.
Then someone already made a version that has a cooldown before a map can be revoted.
