URL of Usergroup PM

Already search for this kind of question that I have, but gives me no luck.

So is there a way to send a PM to Group, but only using a redirection URL?

Here's an example to make my question clearer:

This url: https://help.forumotion.com/privmsg?mode=post&u=7065 will automatically redirect me to PM Sanket.

My question is how about a redirection url to PM a usergroup?

Advance Thanks for the response.

I think you can't. Sorry.

Just with user.
