oh… that fall off you mean. Didn’t you say Drag Net?
Proportionate Edit actually is pretty much exactly the same thing as Point Radial. And the fall off is adjusted pretty much exactly the same and also it has fall off choices which are very similar. Although there are more in Blender. 
I think what you are looking for is Magnet (Radial Fixed) and all of the fall offs similar to that.
I think the closest we have are the Mira Tools. I am not sure if there is a Magnet. But there are some other similar fall offs.
