I have a grass particle-system that I am working on. I would like to establish the areas on my mesh where those particles should exist. Now, I know that I can use Weight Paint mode to draw out my desired area and set the Density to that group.

But is there a way that I can just choose the faces (not paint it out) and set that to become my Density? I just want to avoid the incredibly imprecise painting step that is required for that when all I want is "these four faces".

I hope that's clear; thanks in advance for your help.

In edit mode select the vertices you want, the weight you want, and use "assign" in the data properties:
