Include the ability to pass parameters to a Form that are returned in the response
It would be really useful to inject parameters into a Form, perhaps by passing them in the URL. This would allow Forms to be triggered from an action in another system and then once completed tied back to the same calling action.
Example case would be triggering a Flow when a record is updated in Dynamics 365. This sends an Email containing a link to the Form (including the parameters in the link). Once the form is complete, the response can be captured by another Flow process, and by accessing the stored parameters from that Form instance we can tie it back to the Dynamics 365 record that triggered it, in order to update etc.
