Hello, Ivona.
Yes, this is a challenge. I am sure, that 30, 60, 90 and 120 minutes post glucose challenge free fatty acids are some custom measurements, non widely accepted in clinical practice. Please, correct me, if I am wrong.
I think that the easiest way would be to create your own 2bil+ concepts and set them standard. Other options are painful and not really useful.
Let me know if you need more instructions regarding 2bil concepts. There are some topics here, like I linked above, where you could find instructions.
Merry Christmas!
