Vehicle compatability charts, best way to create or copy? Anything new from Ebay on the subject?

[benzexpert]

I think these Vehicle compatability charts are a big problem for many small sellers such as myself. 
Is there an easier way to create them without adding one vehicle at a time?
Not to mention when I do create them this way, they somehow become corrupted and after spending hours and hours adding hundreds of vehices, they crash and only saved like 70. AARRGH!!! Talk about pulling your hair out!
I see large sellers with HUGE charts and no way are they creating those by hand.
I did find an external paid service that allowed you to copy other people's charts, but then you have to pick through to make sure they are accurate. I did a one week trial with a site that unfortunately I forget the name of and was able to copy a bunch (some of the data was not correct!), but I still have listings with no charts at all, and I'm losing sales. Most of the items I sell are not in Ebay's database of part numbers. 
Has anything changed since I last visited this topic a few year ago? Will Ebay ever create a tool to assist Ebay Motors sellers in the creation or copying of these charts? Whats the latest word on the subject?

Yeah it's a real pain, I would love to hear the answer as well.

Not even "sell similar" from another seller works.
I've been down the same road, spent an hour or two painstakingly adding vehicles, all over a $20 part which after shipping and fees comes out to about an $8 profit maybe.

The one thing I have found is IF you can find the item in the catalog, but be very careful about what you change in the listing... UPC code change may delete the compatibility list, possibly changing the manufacturer field as well, not sure what others but it's the one thing I have found, is using an item that's already in the catalog (obviously still has to be the correct part otherwise you will get vehicle listings that are inaccurate).

Royal, royal pain, this vehicle compatibility nonsense.

So I had to do some searching but the product I used previously was 

3DSeller.  I had a one week trial and it worked flawlessly to copy compatibility to NEW listings. I don't know of anything that copies to existing listings yet.
