How to display content for an Affiliate only

We are using Affliate plugin with Membership plugin.

Is there a shortcode or some way that will allow us to display content only to a logged in user who has already become an affiliate?

Also, it would be great to be able to automatically add a level ( such as Affiliate level) to a user when the user becomes an Affiliate. This would allow us to give additional access just to an affiliate.

Thanks!
