This is just a guess, I am using more of my own logic than knowledge of UE4. 
But I am thinking your BP can only occur in real-time, since it is calculated on runtime.  It's like a live-take only.  Kind of like filming real-life rain, you only get what the scene gave you at runtime.  
I am gleaning what you are actually wanting instead is for the blinks to be calculated, and then plotted out via being keyed-in on the timeline, where they could then be played back per the timeline's instruction.  This would be like CG-rain.  (I don't myself know of a BP way of doing this, not because there isn't one, but because I am only at 10% of understanding!)

Hello Kevin.L
I only found this
Animation Blueprints with Sequencer
I think Bassline can give the right answer.
I have little experience with blueprints.

For NOOBS:

Thanks, everyone for your input I will keep trying your suggestions.


Warped Reality VFX.

I will say this of Blueprints - F%$#!!!!!!!
So, UE4 is very very very unforgiving with hierarchy of folders.  Meaning, move one thing out of place from what it was expecting, and BOOM, you can cascade issues across a whole entire project.
But, this not only goes for materials and shaders, but for Blueprints themselves!  If you change something from where it was placed on a graph previously, or delete and reinsert something someplace else, BOOM.
Do yourself a favor and copy the entire project periodically, you never know when catastrophe may hit.  And, I would say get the skeleton of a project first in working order before you start importing in stuff and/or adding stuff in.

On the flip side, do some blueprint projects along with a Youtube video, you won't regret it. 
An hour may look like a long time of plodding through, but just compare that hour of learning vs 2 days from now where you spend a whole-day wishing you had some understanding.  It gets easier.
So now you know, and knowing is half the Battle....GI JOE!!!!!!!!!

Sorry folks , totally busy right now , but here I show you an Update of the Live Link Face BP for CC3+ Characters , still not finished and take a look at my well organized BP

Look at the right side of the AnimGraph window, on the lower left of the screen, where it says "Preview Mesh Animation Blueprint" 

Is that using your UE4-direct iPhone Blueprint?  
NICE!

Sorry wrong Post.
