If I remember correctly, I set up the options I'm provided with via the "reconfigure" program provided in the directory @BenLoosli pointed you to. With that program you'll hopefully see all the licensing options you have available, and can set up different .psf files to allow you to do each particular function.
First thing you'll have to make sure of is that you have read/write permissions on the directory in question. Our IT folk have locked us out of the ability to make such customizations, so special permissions had to be granted for this purpose.
You also might want to look around a bit on here to see similar discussions of .psf files, to get a feel for how they work. For example, I believe the order in which licenses are listed in a .psf file will determine which are pulled first, etc.
