Copy multiple file at once

Hi, is it possible to copy multiple file using the same progress window?

I know you can do that using a loop, but I'd like to have a single copy without a loop. The purpose is to have in the progress window with the total time instead of instead the remaining time for each file.

Is it possible to do that with the CopyFile function? I don't see how it can be done with multiple file that have not the same name or extension (can't use wildcard).

Thanks!
