After Effects cs6 export

Hello,

i searching on the internet and i can't find something about
exporting in after effects cs6.

Is there any function or new feature to export project to lower cs? For example - cs6 to cs4. I know, that cs5 had function that allowing export cs5.5 to cs5 but many people talking about exporting to lower projects (CS4). And there was a lot of comments and requests to create this feature in CS6 and now i can't find something about that.

Thank you for answer,

Denis
