Any disk utility to copy files across disks with only 1 drive?

Now that I have my CoCo working again, I'm an trying to figure something out. I only have 1 floppy drive. How do I copy a single file from one disk to another without a second drive? I want something like MS-DOS xcopy, which asks to switch disks back and forth. There's the BACKUP command, but it copies a whole disk. If I have a file on one disk, and another file on a different disk, how would I ever get them on the same disk? For BASIC, I can always LOAD and SAVE, but for other files like machine language I can't just LOADM and SAVEM, because I won't know the SAVEM parameters.

This is what I get for not reading the official manual. After finding a PDF online:

COPY "FILENAME" will make a copy of a file to another disk. It will read as much of the file as it can into memory, and then prompt for the destination disk.

I was originally just using some reference website some random person wrote, who only showed this form of the comment:

COPY "NAME:0" TO "NAME:1" , which requires two drives.
