Auction house batch posting question

[Epimer]

I'm not a big auction house player, so I've mostly just gotten by with (previously) Auctioneer or AuctionLite, and I'm by no means an expert on either one.

Levelling through chain running dungeons with the LFG tool means I'm ending up with an absolute ton of low level greens. Is there an add-on that would let me post all of them at a fixed price (after I weed out the "of the Tiger" and "of the Monkey" kit to gouge people), even though they're different items? I can't face listing 70 items individually and am happy to eat some profit losses for the convenience of mass listing them.

Even something to filter by item level or quality. Everything with item level x - y at 5g, for example.
