Automatic incremental numbers assigned in Backburner

I'd like to have backburner assign a incremental numbers to my renders when using backburner.
And if I so choose type a origional name for closer identification. But when doing testrenders I just find it to be one extra task that has to be done.

I don't know scripting so I'm hoping that someone feels the way I do and want's to write one :)
