Phish Threat - Select users randomly

Question

Is there any way, when selecting which users will receive the campaign, select randomly some percentage of my users, insted of selecting all or pick some users/groups. 
 With random targets, the campains will be more efective.

Yes when scheduling there is the Sending Increment which will let you select a percentage of your org to send to over the course of the campaign.
