Matching collision normal for sub-emitter

Hello, I recently wanted to check out sub-emitters as a "bloom" for spray paint hitting a wall, which works great for perpendicular surfaces.

I am using a CIRCLE emission shape to get a flat bloom and the problem is: when the particle system hits an angled surface, the rotation of the sub-emitter suddenly rotates in an odd way.

Does anyone have an idea on how to make my sub emitter always be rotated or adjusted based on the normal of the collision that the particle makes?
