Sorting grade horses more

Some people breed grade horses to make another existing breed (like Anglo arabian) so just thought that maybe when searching for a horse and you click grade horse, 2 drop downs appear for 2 other breeds in its pedigree (so like thoroughbred and Arabian) but also an option for any for people who don’t care (if that makes sense at all lol) just an idea to make it quicker when searching, also not necessarily it’s parents but just somewhere in the pedigree it includes those 2 breeds.

I like this idea. Not sure how it would apply to longer lined horses, maybe it only searches the first page of the pedigree? But then there's the issues of it all being grades hmm. 

crosses with multiple allowed breeds would still be hard to search for, but it's at least a nice start for the simpler crossbreeds. i'd love to search for other pintaloosas! maybe we could have an option to toggle for "only horses with these breeds in their pedigree" or something like that? some people might want to just find a grade horse with appaloosa in the pedigree and not really worry about any other breeds for example.

I love this idea!! Sometimes I just want a shetland/mini cross, not a vanner/Clyde cross, for example. I don't want to have to sort through all of them until I maybe possibly find what I'm looking for.
