Trying to add Fan Speed & Fan State to a Dash?

I can see them listed when I look at the Repair Screen, but when I go into customize a dash I don't see them under Graphic or Text Gauge in the pick-list to add.  

How can I add them when they are there with values in the repair screen but not available in the Pick List?

Thanks, Bill

Here is a pic showing their availability....  

Look harder in the Text Gauges pick list. They are there.

Ah,  I forgot I had to go else-ware to add the fields before I can pick them from the list.  Is there a cheat sheet for finding often used entries for editing an existing dash (actually, not really often used)?  After changing the dash, I have spent quite a bit of time looking for the choice to email my updated dash (which I did a couple months back) but of course i'm not finding it.  Back to the lengthy manual to find that elusive setting/button.  -Bill .

Yes, but it is free :)

What is free?  Surely not the app, as the hardware I purchased would be a paperweight if we weren't purchasing the app with it.
