Lightroom : Move option greyed out for card reader

When selecting "import" and if the source is a memory card, the Move option is not available.

 I found pointers to a previous discussion on this forum. The recommendation was to reformat the memory card after every import with Copy.

I don't find that to be a suitable recommendation. I keep other files on the card such as video files that I don't want to import in Lightroom.

If I import files from the card with "Copy", and then delete the bad pictures from the catalog, and don't format the card, at the next import, these pictures that were deleted from the catalog now will be selected for import again. Really inconvenient.

I'm looking for a simple workflow where the pictures are copied and removed from the card at the same time. I feel it is unintuitive and time-wasting to have to perform a separate action to either format the card, or manually delete the file.

I realize some have concerns about reliability and possibility of picture loss. IMO, this concern applies equally to removable and non-removable sources. The user should be able to choose what works for them. Put a warning in the UI - every time, if need be. Or perform a verification after copy before deleting the file from the original source. Just don't grey out the option altogether.
