Can these be added to AuctionPress

I have just installed, and am about to launch, a Web site using auction press. There are a couple of things missing, I think, that I would like to check on. The following is a list of questions I have been asked during testing. I have had about 25% of the users tell me that without scheduling posts and preview of posts they will not participate.

Do these exist yet, and if not, are they on a list for future development?

1. Is there a way for a user to schedule an auction or buy it now listing?
2. Is there a way for a user to preview the listing before posting?
3. Is there a way to add a quantity to a listing if you have multiples of the same item?

Thanks for anyone’s input.
