key suggestion for improvement No.1 : customize saving path when upload medias.

At present , all our media files uploaded are stored in the global settings of the default path . Actually not very convenient, for example I want to upload media files stored in different directories to facilitate management,but just now can not be realized . For example, I want to save images into “uploads/pictures”; videos into “uploads/videos”; New Year meetings into “uploads/the new years”; xx meeting with clients into “uploads/xx-meeting”; products printers into “uploads/products/printer”…etc. If the saving path can be customized when we upload, it will be more convenient and practical.
