While it is possible that I have simply lost my marbles, I can't figure out how to add a coupon to a directory listing.

I've got one listing with a coupon already, so I knew how to do it at some point in the not too distant past.

I just can't find the Add Coupon button today.

I can see the Add/Edit Special Offer for the one special offer I've got already, but can't see where to Add an Offer and assign it to another, different existing, listing.

I've done some hacks on the module, but thought all were related to the templates and not to any admin functions.

Help.
