Quick Attach Source

There doesn't seem to be a quick way to attach sources.
If I Ctrl-Click a method and IDEA jumps me into a class file, I would like an option to pop up to allow me to attach sources.
I'd also like to be able to attach the sources from the Project Explorer view by right-clicking on the jar

This was highlighted 3 years ago, but didn't appear to get any traction
