If...Then...Else statements for Alert Manager

I owe you folks some news here.  This has been our #1 feature request for some time.  We've done significant research on this FR including surveys and 1:1 interviews with many of the people who voted for and against it.  It turns out that while there are 1400+ votes for this feature, they're votes for several different distinct things.  The two most popular things are actually contradictory: make individual alerts simpler to configure vs make each alert more powerful by making it more modular and complex.

We're still researching this but I have not yet found a solution that does justice to at least most of the people voting for this FR.  You can help though.  If/when you vote for this or if you already have, add a comment with your thoughts on what problem you're trying to solve by voting for this feature and a rough thought of what a good solution would look like to you.  As the community discusses why we agree or disagree, we will get closer to understand the root problem(s) and the solution(s) will start becoming more clear as well.  Or wait longer and I'll figure it out myself! 

Please see my post of 8 March 2017. I think this summarises my main issues.
I have no problems using custom properties within an action to affect the behaviour of that action. E.G. use CP to derive email addresses for email alerts.
What I can't do is use a CP (or other field) to determine which action(s) to perform.
If I had this capability, I would only need for example one node down alert for all my needs. The conditional actions would give me all of the other functionality I need.

Got it.  Thanks.
