Can I rename WP-Admin for entire WPMU network sites?

Hi there heroes!

A few months ago I asked for a plugin that could rename and block wp-admin url. Nastia advised me to use Protect Your Admin, but I'm afraid it is not compatible with WP Multisite.

I'm also using Pro Sites and I'd like to block and rename WP-Admin. Is it possible?

Thanks for your feedback!
