Maintaining Stock in Refined Storage?

[MaxAstro]

This is driving me up a wall. It seems to be a super common question, but none of the answers I have found searching seem to work.

All I want to do is set up something like "hey, if there are fewer than a stack of importers in storage, craft more please".

I figured what I would do is put an exporter up against a downgraded storage drawer and put in a crafting upgrade. The problem is, for who knows what reason, the exporter only wants to craft anything if I don't have an external storage attached to the drawer. And without an external storage attached, I can't access the items. :/

I feel like there has to be a simple solution, since it's such an obvious thing to want to do, but I can't figure it out. >.<

Thank you, that second bit was what I was looking for, I don't know how I didn't find it. I've never used interfaces before and didn't really know what they could do.
