File API for Sell

Hi,

We work with a lot of files, like Orders, Invoices & Contracts. We have made custom widgets to show them to Sales in the browser, however these widgets are not available to them on Mobile.

When we wanted to upload contracts to specific customers via the native "documents" widget in Sell (to make them available on mobile), we found out that this is impossible as there is no API that allows for file to be imported in Sell.

We work with 65 sales people and would love to see this option to be added to the family of API's.
