Is your feature request related to a problem? Please describe.
There are items you post that have been massively undercut by someone. If I post above them, i dont want that to show up on the undercut scan together with everything else. When spamming the cancel macro/button, I accidentally cancel the item that is
"undercut" but not really undercut.

Describe the solution you'd like
2 solutions:

1. easy - add ignore item checkbox or something in undercut scan window + a button to reset filter.
2. harder, maybe? - add an option in auctionator settings to ignore items that were set to lower price at time of posting. This way undercut scan ignores them.

This is unlikely to be implemented, as it would complicate the UI to cope with an edge case.
