Quality of life for trading in /trade

First time i try to reroll watcher's eye modifier and i was wondering how to find watcher's eye 3 modifier (or 6 depend the perspective) minimum to reroll some. There is a line to search for quantity of modifiers but it only apply to magic/rare items.

Couldn't it be for unique aswell ?

I could search for a specific mod and then just write i need 3 (6...) modifiers minimum so it could find easily a right one.

I don't know if it can apply to other uniques but at the moment, right now, for me, that could help.

Thank u xxx
