I believe what you are looking for are the max restock quantity.
type "/tsm" go to your enchanting and down bottom of that go to "options".
Inside of options there will be the max restock quanitity set that to, 1 or how ever many you want. that will change the amount it keeps before making more.
When 25 sell, go to the auction house and scroll through your currently posted auctions. that should put into memory what has been sold and what has not.
Click restock queue and it will only queue what is needed.
That should answer your question if you need more help, feel free to message me.
