Paradies,
I think I understand what you need and I may have a somewhat solution for you. Just ignore me if it won't work for your situation.
I set up my "master" profile to be the template that I use most often, then I set up several "detail" profiles to accomodate various types of auctions that I do (I sell for others also).
So, to start a new listing, I start at "Create New Listing from Master" then only change the "Detail" section to the appropriate one for that type auction.
It works well for me, although it took awhile to set up.
