Template using lzma rather than tar+gzip ?

Hi,

Does anybody know if it is possible to use (Openvz) template compressed with something else than tar+gzip ? Say for instance with lzma (7z) ? I'm using proxmox 3.0.

Since this is my first post on this forum, thanks a lot to all who respond and also to the proxmox team!
