I am wanting to have a plugin activated on every sub-site in my multi-site set up. The plugin would be visible to the network admin, but not visible to each admin of the subsites. (for my case I am wanting to have a hidden plugin activated so I can add custom css code on a site by site basis)
I found a link to:

Which I noticed doesn't list 3.8 capability.
Is there a specific plugin in the premium wpmudev plugins that specifically does this?
