[Add mineral to program database]

Hi!
Does anybody know if is it possible to add a mineral to the program database? I would like to add crandallite, CaAl₃(PO₄)(PO₃OH)(OH)₆.

I am trying to generate mineral phase diagrams that include crandallite and apatite.

According to the reference attached (Dill, 1991), crandallite should be formed in the presence of HPO4--, Al+++ (Gibbsite), and Ca++ in an aqueous solution (25º C and 1 atm). However, it seems crandallite is missing in the program database.

Cheers
