Vehicle Replacement and Addon Combined Resouces(Extrafiles problem)

Hi. im rather new to the GTA Servers, but i have gotten true the worst parts i guess. but i have been messing around to create better resource files and such on my server. but im running into a problem and now im coming to here. to ask if its even possible at all… So then we make resources with multiple cars and such. most of them are just simple replace files but some of them got extra modification files like vehshare.ytd,window_lf.cwgv etc etc… but putting them all in one streaming folder would replace them. so my question is there a way to get a single resource to have either multiple streaming folders or have sub folders like we can with lua scripts and meta files.
