Packing multiple images files from outliner

Currently, we have the option to:

1. Pack all image files from the File - External Data - Pack Resources
2. Pack a single image file from the Image/UV Editor.

Option 2 is time consuming when we have to pack many images - open each one, click on image, click 'pack'.

Being able to select all image data blocks in the outliner and packing them at once would be a time-saver.
