Question Temporary Rank for WorldGuard area Access

Apologies if this has been discussed before, couldn't find anything obvious in the listings...
Anyway, brief description of what I'm trying to do:

Restrict access to an area tied to Voting duration... "Vote and gain access to the Voter's Lounge"
Player votes-> Player promoted to "voter" rank-> voter gains access to lounge.

Where I'm getting stuck is at the 24:01 expiry when voter needs to vote again, how do I remove access to the lounge until player votes again preferably with an alert?
Vote expires --> Player loses rank --> Player needs to vote again

What I have going so far, Group Manager with Voter subgroup, WG bars access to anyone without voter subgroup, votifier grants voter subgroup, access granted... Now, how do I take it away after 24 hours without stripping all ranks (ie, a donator rank still needs to vote for access but doesnt lose donator rank).

Anyone know an efficient process string?
