UE4 Niagara - Module help


I have specific issue with Spawn Burst Instantaneous module.
In my game I have two state slow motion and normal and don’t know how to change this module to operate with constant rate ( emit particle with constant distance in time ) independt from slow motion. Somebody can help me with this problem? Maybe is there easy fix to do this? Or should I completly change data flow inside this module?

I think you will have to make your own spawn module, but it depends how your slow motion works. Can you give some more information?
