There is a little problem here. 😐
As you may know or you may no know to copy/move files with admin access requires that the process should be started with elevated access.
TotalC/other commanders have some helpers (e.g TCMADM64.EXE, TCMDX32.EXE) that do this in background but this also make application unportable or you need installation.
MyCo will have that feature too, but without these helpers so it can be ultra portable (just a small exe file).
This is a little bit trickier to implement, but as you said there is a workaround for that and for that reason this feature is not in the priority list yet. 🙂
