How to automatically name output files with "bin" name that comps are in?

Hi everyone,

imagine this project panel:

> COMPS

>> 01_Long-Version

>>> Comp 1a

>>> Comp 2a

>> 02_Short-Version

>>> Comp 1b

>>> Comp 2b

> ASSETS

>> Solids

Now I want to render all 4 comps, but they should be automatically put inside a folder corresponding to the "bin" names that they're inside ("bin" being the AE project folder structure). So my output folder structure should be:

/Renderings/01_Long-Version/Comp 1a

/Renderings/01_Long-Version/Comp 2a

/Renderings/02_Short-Version/Comp 1b

/Renderings/02_Short-Version/Comp 2b

How can I do this? I know that the render queue has this "Output To:" dropdown, but there is no option for this (but lots of stupid alternatives).

Thanks in advance,
