I am not an expert in this but I use turbo lister and i list directly on ebay. Is it possible if you have a listing already up with those same players to copy and paste each name from current listing to turbo lister? You would have to still only be able to copy and paste one at a time tho, have ebay open in one window and turbo lister window open. I don't know if that makes sense, but it still seems like the only way would be to copy and paste one name at a time. Or you could do a listing on turbo lister put all the names in and just duplicate that listing. You can make as many duplicates as you want and then edit the stuff you need to edit , like the title, description, item specifics, etc. I would have done that before when doing variation listings for my husband on his turbo lister on his computer. I just duplicate the listing before I add the pictures. Otherwise you have to delete the pictures and then add the new ones.
Don't know if that helps it all, but seems that making a duplicate listing in turbo lister if using same ball player names would be easiest and edit the duplicates with the new information and pictures. Hope helps some. Good luck. Wish there was easier way to do things on here sometimes and also I wish there was more categories that you could do variations on. I list a lot of train items for my husband and certain categories you cant do variations, same in jewelry where I list on my store. Auto parts is another one. I hate having to use more listings for something that is very similar, just a color difference or something and you can't do variations in the auto parts section. That is the bulk of my husbands store and of mine also. Very annoying. They need to update things that would actually save ppl time rather than some of the pointless updates they add or changing the shipping page. They don't even list all of the USPS boxes !! I use all of them too with all different orders, some make more sense price wise . Like I sold a huge lot of jewelry, person ordered several separate listings and I could fit all in a large flat rate box and the option wasn't there!
Sorry for rant but so many things wrong with this and make it that much harder and that much more time listing. We could list more too if it wasn't so time consuming they way they have it set up. You should be able to copy and paste and be done. I have no idea who the hell runs IT here.
