Instead, more generically, an ability to either multi-select items for sale to the vendor, or a "Sell All To Vendor" button with the ability to mark items not-for-resale.
Personally, I would prefer the latter option. You designate the boss mats you just collected as "Not for resale"; then you open up a Trade window with a merchant and the boss mats you marked don't show up. You only collected some other guard creature mats, and those you want to sell, so you click "Sell All To Vendor" and it sells everything to the vendor that can be sold.
The first time you use this button, a warning should pop up to let you know that you could accidentally sell something you didn't want to sell. It should be possible to disable/hide this warning from reappearing.
Working on a second Jewel master, and the rest not far behind, you learn how to optimize the selling of vendor trash, particularly small items like jewels. I'm comfortable with the way things are now, but there is almost always room for improvement in anything, and this is one area that -could- be improved upon.
