Could be possible to implement a something for specific rares?
Ex:
Rare Spear 1h
2h Staff
1h Sword
...
If you're trying to save specific items in order to use in the Cube (reforge as legendary), I wouldn't worry about it.
The bot would find so many, so fast that it would really burn up your stash space quickly. It's better to just forge items at the blacksmith and use those.
See the post here for examples:

Until there is a feature created in the 2.x version most people are using that will auto-upgrade rares to something for you, auto-saving rares will create more issues than it will fix.
Besides, I have rolled 2 brand new characters (Barb, WD) and had all required pieces for end-game builds within 2 hours each... Including solo leveling myself with the bot. This was done using the cube along with blacksmith/jeweler to roll all items.
It cost a total of 5000 deaths breaths, 500 forgotten souls and about 11000 each of veiled crystal, arcane dust, reusable parts.
If you're worried aobut how long it would take to farm all of that, get a speed build going and running through regular rifts on lower difficulty for a day or two.
