Ruleflow groups allow you to group rules together and rules inside a ruleflow group only execute when the ruleflow-group is active.  You can use ruleflow groups inside a ruleflow but they can be used outside ruleflows as well.  You could manually activate and deactivate ruleflow groups using workingMemory.getAgenda().[de]activateRuleflowGroup(name).  You can decide whether a ruleflow group should auto-deactivate if it contains no more activations or not.
 
I guess it's not exactly what you are looking for but it might be useful.

Subject: [rules-users] Agenda group doesn't stay set?

 
I'm writing rules in different agenda groups and witnessing something curious.
 
Right now when I put my fireAllRules() in a callback that is triggered every couple of seconds I have to do this:
 
Callback executes on receipt of a heartbeat message:
{
   session.setFocus("my_agenda");
   session.fireAllRules();
}
 
What I would prefer to do is this is set my agenda group external to the callback so I have the liberty to simply use the callback to execute rules on whatever agenda I give focus to elsewhere:
 
Callback executes on receipt of a heartbeat message:
{
   session.fireAllRules();
}
 
But this doesn't work.
 
My understanding is that unless you explicitly set the agenda-group each time, then fireAllRules() resets your agenda group to "MAIN"?
 
Is there a way to get the session to retain focus on the agenda group I specify until I see fit to change it?
