This is just a rephrasing of my earlier suggestion ("Conditional bidgroups"). I would really need this feature. Because it is interesting to combine items for saving on shipping, I would like to be able to cancel all bids in a bidgroup when the N first snipes are lost. This is the same feature as bidgroups replacing "first N bids won" by "first N bids lost". This should be quite easy to program. Thank you for answering to my request.
