Is there a way to make the C1 import process only load DNG files and ignore matching JPGs? Most of the other importers handle this easily and make the option obvious but I can't find this within C1 Pro. Am I just being dumb or is this feature there and I'm missing it somewhere?

I know I can import and then clear out the capture dir but I'd prefer to avoid the time & space during import, plus the chance to mess things up deleting files later.

C1 Pro v5 btw.
