Can not change destination type in Redwood Purchasing

Summary:

I have enabled Redwood Purchasing in a lower environment to begin testing. When I create a manual PO, I do not have the ability to change the destination type for an item in our catalog that I want to expense out to a department. We currently have this functionality in the classic version. Will this be on a future release or do I need to pose this as an idea?

Create Purchase order for catalog item. Change destination type from "Inventory" to "Expense". When I click Edit in the schedules area where this field lives today, the field does not become editable.
