add COPY option in Library tool when moving images

What problem do you see this solving?

On import into Capture One, all NEFs are copied into folders named (LOCATION)_(YEAR).

In a second step, selected images are edited and exported into a new catalog (CLIENT)_(DATE).

This catalog is stored on another disk that I can take to clients.

Not only do I want the catalog on that portable disk, but also the originals so I can work when I am away from my office.

I select all images in the catalog (CLIENT)_(DATE), and create a new folder (CLIENT)_(DATE) using the Library tool.

And that's where Capture One gives me problems:

There is no way to COPY the NEFs from the original location to the new folder. Instead, they are MOVED, which means they DISAPPEAR from the original location and break the link to the original catalog as well.

When was the last time you were affected by this lack of functionality, or specific tool?

Regularly.
