Is your feature request related to a problem? Please describe.
No issue per se. Automating item sales based on Baganator categories would be big.

Describe the solution you'd like
Adding options to (custom)categories to automatically sell {all items; 10 items at a time (buyback cap)}

Describe alternatives you've considered
Using additional addons would be possible (if any exist). Having to re-configure the same filter criteria already in place for (custom)categories would be a bummer.

With a vendor open, you can right-click a category heading to sell 6 items a time. This is part of the Transfer feature, that allows you to transfer (by right-click) to any other container: bank, new mail, trade, or the scrapper.
