Hi Eric,
As far as I know this isn't possible, though I'm happy to be corrected if anyone knows better.
The alternative is to ...
Use File/Open ... selecting all the graphics you need will open them all simultaneously.
Then use Mutliple Printing.
Drag the images from the left over to the workspace and resized as desired.
Images already dragged to the workspace can be arranged automatically by selecting Auto Arrange from the Preferences menu.
Hope this helps.
