URL format/parameters for Mass PM

[dink337]

Is there a way to format the URL of a PM to allow for multiple user id's in its parameters?

For example, the standard URL for sending a PM would look like:
.../private.php?do=newpm&u=101

Can it be formatted to allow for something like:
.../private.php?do=newpm&u=101&u=102&u=103&u=104

I'm trying to see if I can build a link that when clicked on, will open a new PM message with the recipients field pre-populated with a list of users. I'm not looking for a Mass-PM plugin or anything like that, I'm just trying to see if I could setup the parameters in the URL itself, to work for this.

Is it possible? Can this be done?

Thanks in advance for any help offered
