Bid on a stack with one character, sell one at a time with one or more others. Leave the bought stack in the "bid" slot. Use a selling price that is too high for others to interfere. Drawback: market fees.
Enhancement tables in a personal SG is a better solution.
If you just want to store them, just email them to yourself. This is only good for < 60 days, however.
Bit cheaper than buying an enhancement table.

I only mentioned storing to be comprehensive in the concept, so don't get hung up about it guys. I'm more interested in being able to sell a stack of enhancements in one slot. For example, if I was working the Common IOs. It would massively increase the volume I could put up (subject to salvage availability, of course) and at the same time, free up slots for other purposes.
Teams are the number one killer of soloists.
I keep wanting to go to Suggestions and Ideas to suggest changing the Enhancement Tray to an Enhancement Window, like the salvage one, with tabs for SO, TO, IO, etc, and that allows identical enhancements to stack, again like salvage does. Once this is done, the stacks of enhancements could be moved to the market window at once, permitting the stacks that you want.
Unfortunately, I can tell you with 100% certainty that such a suggestion would be instantly flooded with demands that the new window have a larger capacity, or the ability to increase it (as is possible with recipe and salvage inventories), or both. And that's a can of worms I don't want to be responsible for opening.

With the new market interface, you can bid/buy a stack of crafted enhancements in one market slot. Inspirations too. But, is there a way to drop or otherwise cram a stack of enhancements into one market slot for selling or storage?
