Ability to specify full file path (not just file name) in command line

In the Wiki for the command-line, there is a note:

Note: There is a known bug err "limitation" that you can only specify the name of the file (not the path). Therefore if there are multiple instances of the file inside the msi with the same name and you want to extract that file there is no way to specify which file to extract. If this is a problem for you report an issue and if I know it is important to someone I'll take the time to make that work.

I could use this capability, as our installers have dlls with the same name (in separate folders), for different languages, and I need the ability to extract all of them.

Thanks in advance.
