Yes, put it in the $Conf{DumpPreUserCmd} setting.

There is no file-level equivalent. Backuppc does hardlinks, not
deltas and only de-dups at the file level. The best you could do is
to script a restore from these backups and point backuppc to the host
holding the restored copy with the ClientNameAlias setting. Then when
you remove the ClientNameAlias and back up the real targets you would
have initial copies for rsync to work against.
