executable php in directory creation

Firstly, thank you so much for the outstanding module and a brilliant player.
It would be 'neat' if administrators of a site could execute php when creating a directory. At present they can create a folder of course, but all vids will go there. Neater would be like imce does, which allows me to execute this code - php: return 'users/'.$user->name; .
This is just a request suggestion of course , in a pursuit of a neat backend. Now i'll just sneak off and try to learn how GIT works so I can be more proactive. Thanks

OH p.s. i've tried tokens in the fields file directory but that doesn't work.
