Change suspend type from kde menu

[Valerio Vanni <valerio.vanni@inwind.it>]

Is there any way to change the way system is suspended from kde menu and 
from power saving in kde settings?

I mean changing the command issued.

I don't know exactly what the default command is, probably systemctl.

/usr/sbin/pm-suspend works better with kernel modules, and I'd like to 
use that
