Remote post handler should be able to capture return value

Problem

The remote handler is intended to send form data to a remote URL. A typical usage is sending data to an external CRM, issue tracker, ERP, etc. It is currently not possible to capture a return value from the remote handler. This could be useful if the remote handler returns an ID or URL related to the created Customer, Lead, Price Quote, etc. The success message could then become

Your request has been sent. You can consult the status of your request here.

Possible solutions

I think 2 possible solutions seem reasonable:

• The return value(s) could be exposed as a token(s) in the success message.
• The return value(s) could be saved as (a) form value(s).

Optionally parsing the return value as json is probably a good idea, but even just one value would solve 95% of the use cases
