It would really be helpful to be able to put a close time and be able to toggle whether you want zeffy to extend a last minute bid by three minutes or if you want it to close at that time and not have to do it manually. I work for a charatible music festival and we need our auctions to close exactly at the set time no mater if there is a last minute bid or not. So that we can process payment and get the winners to their best seats. This is a time sensitive thing for us. It would be good if there was a toggle switch under the start time end time portion that allows for auctions to hard stop, or go into the 3 minute extension. This would really help us out a tonne!
