can you customise a Saver Filename with an expression?

Hi there,
Just wondering if it's possible to customise a saver filename with an expression.
I'd like to make it so the saver filename is the same as the name of the scene.
Something kinda like this Project/OutputDir/$SCENENAME$_.png
I do this in Houdini a lot and it really speeds up creating output nodes.
Thanks,
Pete
