Someone help me organize my horses!?!?!

I am so bad at organizing my horses. I can buy as many divisions as needed but I have like 50 tbs, some I will breed, some I will not, and so on with all the breeds I have. So, what is the best way to organize so all the breeds/disciplines are together for ease of daily training? 

If you aren't sure what I mean go check out my divisions and horses and you will know then, LOL. Does anyone have any suggestions or tips?

you can go to my page and see how I have mine. I think I need to expand mine a bit. but what I did is group them to the disciplines. then what I did was if I had more than 6 breeds I broke them up.
