Copy several histogram in one root file

A related issue:

if I do:

rootcp source.root:*pattern* dest.root 

It complains:

WARNING: Same name objects aren't supported: 'some_name_with_pattern' of 'source.root' won't be processed

The object some_name_with_pattern usually has multiple versions: ;1, ;2 etc. I would like to copy just the latest version but I don’t want to hardcode the version and would like to use just *pattern* while copying.

Here, @couet said:

Note: If an object has been written to a file multiple times, rootcp will copy only the latest version of that object.

does that mean, despite the warning, 'source.root' won't be processed, dest.root will still be good?
