Cryptomatte for separate objects in the same scene

Hi everyone,

I have a scene with two objects - a character and a particle simulation in front of it. In the compositing, I want to add a glare effect both for the character and for the particles simulation but each with different settings of course.

Below is a SS of the glare effect that I added to my character already using cryptomatte (excluded the eyes of course):


Now, I also want to add another glare effect with different settings to the particle simulation. How can I do this?

P.S. Of course I can do this easily by using separate scenes and putting them together in compositing but when I do this, I lose the reflection of the particles simulation on the character and I don’t want that - that’s why they need to be in the same scene.

Any help would be greatly appreciated!
