Allow survey exemption list to be a living list instead of a CSV

We can knock someone off a survey but it would be nice to be able to add someone to the exemption list easily/dynamically instead of having to upload a csv. 

Hey @andrew_cummins , thank you for your post. The Product Manger will take a look into this and get back to you to let you know if this can be done. 

Hello @andrew_cummins 
what could eb the reasons for someone to get into exclusion list apart from bad sentiment, churned, blacklisted.?

The main reason for us is we get emails from customers asking to be removed from a specific journey. We have journeys that are waveless meaning it is perpetual journey and the customer enters in every six months.

@andrew_cummins ,

we are looking at providing on option to build custom exclusion lists that you can attach to a program. The feature request has been added to product backlog for priorotisation.
