Thanks Bert. I'll work on the OCD
Interestingly, working on another issue in another post I've inadvertently come across the answer to the problem:
choosing to delete the imported item doesn't remove the actual actual file from the patient's imported items folder IF that item is being "previewed" in the imported items page, but if another (or no) item is previewed, it does delete it.
I may take your advice and just let it be though, or at least not actively change the preview to properly delete the item ALL the time, but accepting it as a safeguard.
Thanks
