Hello, first post. Here we go

I was searching to see if the existing HS cookies contained contact list membership information, apparently they don’t.
Could there be any way to achieve this with some custom setup? I would like to use it this cookie value to further personalise page content in a way I’m currently unable to with smart content alone.
Here’s a simple scenario: user has subscribed to a newsletter, let’s store this info as a list membership value into a cookie and use that cookie information to hide the newsletter subscription box from anyone who has said value stored.
If this has been discussed already, please point me right direction and delete this. Thanks.
