How to implement a "switch" in a rule set? I would like to make a rule set that functions as a switch with breaks in PHP.  Example:


Rule 1- User has role A, redirect to 1
Rule 2- User has role B, redirect to 2
Rule 3- User has role C, redirect to 3
Rule 4- no conditions, redirect to 4


In other words:


If a user has role A, redirect to 1.
If a user has roles B and C, redirect to 2.
If a user does not have roles A, B, or C, redirect to 4.


Is there an easy way to do this in Rules?
Declare a variable called "done".


First rule in the set checks for role A, sets done and redirects. 
Second rule in the set checks if done is true, and role is B, sets done and
redirects. 
Third rule in the set checks if done is true, and role is
C, sets done and redirects. 
Fourth rule checks if done is true,
redirects.
