Question Adding smoothness/roughness 2D texture in ShaderGraph

Is there a way to add a smoothness 2D texture and pass that as property to PBR shader node to control smoothness/roughness? In the standard shader we had options for roughness and smoothness with texture property. However it is very confusing how to achieve this in shader graph.

 

Try using Sample Texture 2D node and sampling from it with UV input and passing RGBA or RGB output to smoothness/roughness.
