Importing a folder into the media library

Hello,

I've set up a folder with all of the multimedia files for my storyline course on my computer. Is there a way I can load the whole folder at once into the media library? So far, it looks like I have to go to the tab for the kind of asset (graphics, audio, video) and then shift click select each of the appropriate file types to add them.

I'm hoping I've missed a better way to do this.

Thanks for your help.
