Couldn't find way to add Subscribed Counties and Total Subscription Price values under "Probabte Leads Subscription" tab/REI print

I’m creating contacts using infusionsoft APi. In “Probabte Leads Subscription” tab, there is REI print where we can define Subscribed Counties and Total Subscription Price. I want to ask if it is possible to give this info using REST API or XML-RPC? If yes, what are field names or anyother endpoint…? Thanks.
