CSWP Offer for Subscription Service - for each license?

We have 18 seats of SolidWorks at our location.  I would like for the others in our office to be able to take the CSWA or CSWP but all the licenses are registered to me.  Is there a way for me to get vouchers for the others using the free code?  If so, how?  Do I need to talk to someone at SolidWorks?

Any help would be appreciated.  Thanks!
