once you have control of auto-post, can you shut it off for pos module?

One of our retail staff has started doing some bookkeeping and they now have access to Auto-Post.  It defaults to off for book keepers.

Is there a way they can have it save as on/off instead of defaulting to off?

The irritation arises when they turn it on, login to a POS session (which defaults it back to off) and then they have it prompting them whenever they make a sale. We're hoping the setting can be toggle-able and last setting can be saved.  We've run into an issue where sometimes people close bv after a sale, before posting the journal entry and then we need to manually fix things.
