can each sellers have own uploading directory?

Hi, I'm using multi seller module.
when a seller add/modify their products, all sellers are using same uploading folder through the description editor. so a seller can delete other sellers images for product description.
can each sellers have own uploading directory? I can modify php code, give me a clue please.
