Wild media server (UPnP, DLNA, HTTP)

I would like to propose coding in multiple selection (with shift key for range and ctrl for multiple choices) for directory drag&drop from "media resource folders" to collections.
Currently one needs to move directories one by one and with hundreds of directories under "media resource folders" it takes hours.
Also right click on directory in "media resource folder" could have option "add to collection", without a need to drag&drop directory in global view.
