Welcome to the forum!
Sapien doesn’t make subliminals. They do morphic fields, which are different. You can read more about what morphic fields are
Here: Official Sapienmed FAQ (Updated)
and here: Awesome Article Written About Morphic Fields & Sapienmed
At this time, I don’t believe Sapien Med are taking requests for a custom field. You could post your request in The Requests and Fields thread, and maybe they’ll make a commerical product for sale.
