Particle emitter origin animation?

Hi all!

Is it possible to animate the Emitter Origin values of a particle system in a blueprint?

So I don’t want to attach the emitter to a moving object but rather would like it to spawn the new particles along a straight path over time (Like starting with originY=0 and in 5 seconds reaching originY=200). This way the older particles would slowly drift on their path until their death and not dragged with any moving object. I hope it’s clear what I’m after. Like the emerging smoke trail the roadrunner leaves on the road.
Thanks!
