Hey Tim,

you need to edit the fixtureTypes.xml file, which can be found when going to Programs > Catalyst, Select Catalyst Application and right klick "Show Package Content"
Then go to resources and look for the File Fixturetypes.xml
This File can be edited in an XML Editor, I would recommend Jedit, as it's freeware and runs on Mac and PC Systems.
Then you can copy one of the existing files (Pixelline 1044 would be good for you) and edit it to your needs.
It's pretty the same like building a library for a Hog II.
The Master Intensity (MINT) can be set by default to full, as you might see in the different profiles.
The first time is a bit of try and error, but once understood you will be quite fast with it.

Best
