[Membership 2 Pro] Membership 2 pro and Mailchimp GDPR Compliance

Hi There
We currently have our membership integrated with the main chimp add-on so that someone who joins as a member automatically gets added to the mailchimp list. In light of GDPR we will need to add a tick box so they explicitly consent to receiving marketing emails from us. The functionality is not there at the moment but are you planning on adding it in to membership 2 pro? I'm also using a buddypress registration page as we have additional field such as address that we capture.

If you're not planning on adding this as standard functionality can you advise how it can be achieved?

Many Thanks
