Feature request: default COS replacement

Hey,

I'm happy with the External Restore default behavior, which is to restore all COS with a "_restored_" suffix. It makes perfect sense.

But could it be possible to add a switch, at least to the command-line tool, to force the replacement of the default COS by the one from the data being imported?
That would be useful when restoring entire domains to a brand new server where the default COS hasn't been customized.
It would avoid having to replicate the "new" default COS's settings manually into the existing one since renaming/deleting of the default COS is impossible. And avoid having to change the COSId for all the accounts that are using the default one (easily done with a one-line command, but I guess I'm lazy!).

Thanks,
Nico
