Hair Attribute Painting

Since Geometry Nodes are a thing, hair attributes have become very useful for making hair systems. It would be helpful to have a brush for painting an attribute, instead of having to do it in edit mode.

I thought of this because I needed to have an attribute mask for a noise and clump "modifier" factor and I realized how unnecessarily annoying it is.

Currently we need to use the select brush, go to edit mode, create an attribute, select it if it's not selected, click on Curves then Set Attribute.
