as I understand, you would like to bulklist upload your domains to your own domain auction. Are you the only Person starting new auctions?
If so, you could easy adapt the subsection to have certain stuff already put in the fields, editable, but already there, so you just have enter, b.Ex., domain-name and price, to click a buttom, then go a double step back, add another domain-name and click again.
This would be the easiest thing.
If you are not the only Auction Starter, you could create a separate Sub, containing your "premade" Content, but for such, you need to make some slight adaptions to your congigurations.
This would be second second easiest.
Or then, you learn a little about Perl, take an existing MB Bulkloader and adapt it to what it takes. There ist not som much difference anyway.
This is the hardest way, but then, you have a real Bulkloader.
just my two cents
