Hey!
What you are asking for is basically a Scattering tool. I don't know if I will ever integrate one, although it is frequently asked for, reason being that many free alternatives exist, such as SpatialGardener, Zylann's Scatter, ProtonScatter, or the built-in MultiMesh "populate surface" tool. At the moment, I can't achieve the sophistication of SpatialGardener if I tried tried to integrate something similar, so I advocate for using a different tool, instead of waiting for AssetPlacer to provide the functionality.
I hope this helps!
