Attach file to Desk Ticket from Creator App

Attach file to Desk Ticket from Creator App

Is there a way to pass a form that is uploaded from a Creator form into the Desk app?  I am able to pass all the other fields with no problem, and I found that you can do this with the CRM app using the following syntax:

<CRM Response> = zoho.crm.attachFile(<Module Name>,<RecordID>,<file upload field>);

Is there any way to do this with the Desk App instead?  There is no documentation of this that I could find.
