How to "fade in" forces on a per-particle base?

[robertfreitag]

Hello, I'm stuck with a problem I cannot figure out on my own. I'm trying to "fade in" a force. 
Back in the Pflow days the force operator had a "offset influence" where you could "Sync by" for example particle age. 
I cannot find any equivalent in TyFlow on my own. 

So what I want is: Particles from event A are getting tested and sent into event B, 
then I want the force in event B to successively add over a couple of frames for each individual particle, not for all at ones.

I did see the "timing" rollout but as far as I understand it, this only allows me to set the operator 
"on" and "off" by for example event age or particle age.

Any tips would be helpful. Thanks!

Not possible yet outside of the Script operator, but you can see timing controls for operators is on the todo.
