Multisite user management

So I have a Wordpress multisite which is only going to have two sites in it.

I have two user types - standard (free) and gold (paid).

What I would like to do is give users the same user lever over the whole network - so if standard users sign up they are given standard access over the whole network, if a gold user signs up they are given gold access over the whole network.

Currently if a standard user signs up they get standard access to the whole network through Wordpress’s own ‘Multisite User Management’ but if a gold member signs up they are given gold access to the site they signed up to but only a standard access to the other site, again this is (I believe) given through the default Wordpress ‘Multisite User Management’ functionality.

Is there anyway this is possible to manage through s2Member or is this something that will need to be handled in another way?

Any advice / direction on this would be greately appreciated as I’ve come to a bit of a dead end trying to figure this one out on my own

Thank you for your time looking in to my query!
