Using multiple restriction shortcodes for one piece of content

Hello,

I am using Membership to restrict content, and have run into an interesting situation.

I want to limit a piece of content to if a user is in neither of 2 specified groups. For example, I would like a way to use the shortcodes as such:

[not-level-tour-competitor && not-level-junior-tour-competitor]CONTENT X[/not-level-tour-competitor && not-level-junior-tour-competitor]

Obviously, this would not be the right syntax for doing something like this, but is there any way to accomplish this in a straightforward way? My only guess would be to embed the shortcodes within each other and write the content twice.
