For trinity:
Under "items" there are 3 tabs underneart the one that says "items".
Click on the one that allows for salvage rules, turn off "blue, white, rare" to "none" then click "salvage all rares". (You can make your own adjustments)
This will tell the bot to salvage all items, but because you have disabled rares/blues from being salvaged it will now go and sell them. EZPZ.
Make sure to turn on pick-ups for items you wish in the other tab (Pickups)
