How to Set Repeating Group to Expire at Specified Time

Hello,

My app lets the user create a group request that can be joined by other users.
It specifies the Place, Date, Time, # of people needed, and Other information.

My question is this, is there a way to have the repeating group request expire after a certain amount of time or after the date has passed?

This is how the repeating group looks now, I would like to add a part that says, “Expires in (and the time left to join)”

Thanks!

Anyone have any idea how to do this?
