Help - Unable to effect alpha of VFX graph's particles when using dissolve shader

Hey there!

I’ve made a VFX shader graph dissolve, and for the most part it’s working fine, but i can’t seem to control the particle’s alpha in the color/gradient blocks - it only seems to control the actual color. I know in shuriken i had to hook it up to the vertex color to get that control, is it different in VFX graph?

Any help would be greatly appreciated - Thank you in advance!
