It is not supported OOTB. You might have to write your own end point to do this. For example when you create a site using blueprint /bin/wcmcommand get called with cmd=createSite which internally calls CreateSiteCommand class which then looks for your configurations from input form and then create site. In order to include DAM or tags or any path, you might need to extend this and with your own end point, then update create site form action to point to your end point. Hope it will help.

Unfortunately not all classes required to extend LiveCommand is exposed or extensible. You might have to Extend com.day.cq.wcm.api.commands.WCMCommand and write your own performCommand. I have created a ticket with daycare to exposed some more classes under com.day.cq.wcm.msm.impl which is exposed as service but not exported by any bundle. That will make your life easier.
