When i was obsessed with getting it to work under single action
I found this post
But it was using javascript and not events
So i forgot about this post
I later did manage to come up with formula that will do it
Now i was looking for something else for another user
And so i will just share my discovery here
It is not elegant but for most ppl needs it will be perfect
It is long wall of text but it does what it is meant to
