Query 'Particle Texture' input in an emitter shader

Hi!
I'm setting up some particle shaders. By default, when adding a new empty material to my emitter I see there is already an unassigned Particle Texture property. Is there a way to reference this texture property in Amplify even though I haven't placed a texture in the graph yet?
