Hi @adamnewton 
Thank you for your the detailed description. To be honest, this feature will be available with the release of action buttons, but at the moment I can suggest a workaround to you, though the workaround would only work if you’re on a Business plan.
Here is what I would personally do:
- I would create two user groups in the way the same user gets included in both of them, though the criteria in the User Group conditions should be different.
a) a user groups that should be able to edit requests
b) a user groups that should be able to edit responses - Then I would create edit permissions for each user group so that user group 1 could edit requests, and user groups could edit responses
As a result, by enabling the corresponding user groups edit permissions for requests and responses block, the same user can see the different fields in edit pop-up for each block.
Hope it helps
