Get Imported Asset Source Path Inside Editor Widget

Is there a way to get a source path to an imported asset inside of an editor widget?

I’m trying to create an editor widget that can import an FBX, then related textures, create a material, then put it all together. To automate that whole process. I’m using the “Import Assets with Dialog” node but I can’t find a way to get and store the path to the selected asset so I can feed it back into a “Import Assets Automated” node to grab additional assets.
