Reservation notifications

Can you add 2 features. I’m interested in a spot that is reserved and would like to know when that reservation expires (is it tomorrow, a month from now, next year)? Will it be extended or expire?

1 - have a feature that shows the date/time the reservation expires
2 - have a feature that can notify a user once the reservation expires, so they can take the spot.

Please let me know if you add these features, since I’m keen to get that reserved spot.

Thanks!

Ryan
