How can I keyframe a particle emitter's position?

I have a particle system in Cascade and it uses several emitters to create the effect I want. What One of these emitters needs to do a somewhat specific move in relation to the rest at a specific moment in the effect. I’m not very well versed in Cascade, but in After Effects or C4D (I’ve mostly a Motion Graphics for tv background) I could just keyframe the position of the emitter to create the effect I’m looking for. How do I do this in cascade? I wouldn’t mind migrating to Niagara if it’s the better solution.

Thanks in advance!
