How to render a single form, for two or more schemas.

[itsvick]

We are building education credential registry front-end using Sunbird-RC. We want to implement form to register school as well as principal in one form and looking at the form configurations we can only add one schema API in one form JSON. Has anyone implemented this before, multiple schema in one form?

Can we make changes in Sunbird RC form configuration for this?
