Explicit Role Tagging AND/OR where only mentioned roles exist

A way to zero in on users whose roles match the ones mentioned. 

For example: 

If my roles are @Nitro, @Admin

and 

Another uses roles are @Nitro, @User

I can target only @Nitro users that are also @Admin

ie;  "@Nitro AND @Admin  Check out this link"

Another example with World of Warcraft where I may want to ping all the class roles of a specific raid team role would be:

"@ThursdayRaidTeam AND @Priest OR @Shaman OR @Druid
Check out this link"
