Need a smoke effect to linger after collision

Hello everyone!

I’m making a fire extinguisher particle effect and it needs to have collision. I’ve set the emitter up below to bounce off surfaces, but it looks odd when repositioned in any way, as the colliding smoke follows the end of the emitter, whereas I want it to linger.

I’ve racked my brain and cannot come up with a solution to this in all the module options I’ve tried. Can anyone point me in the right direction for the setting for this?

Hi - did you end up finding a solution for this, as I am currently trying to achieve the same thing? Cheers
