Inviting Guest Reviewers is currently a little bit of a pain

When inviting guest reviewers we need to add the email and name of the reviewer. 

Imagine having a project with multiple tasks and multiple deliverables where you want to start a guest review for each one, and imagine that you have 3 or 4 people from the client side that need to be added in each one.
that's an inefficient series of copy pasting , or worse, typing people's emails hundreds of times.

It would be amazing if we had a quick fix like so:
the fields in the form could "remember" previous entries just like any typical "email" or "name" input box (implementation wise it's probably just a matter of changing the "input-type" in the html)

I guess a longer term fix would be to allow pasting multiple emails i.e. : "Wrike <noreply@wrike.zendesk.com>, Yannis <yannis@testemail.com>" and parse it automatically into reviewers...
