I would like to be able to grab more than one image at a time to import onto a canvas in XCS.  According to XTOOL support, after clicking on the image import icon in XCS, I should select one image file and then press the COMMAND key (MacOS) to allow me to select other image files.  This does not work.  I tried CMC, OPT, CNTRL and SHIFT.  None work.

Anyone know how to do this?  It's not a show stopper, but it is pain in the butt if I want to import several images and have to do them one at a time.  Time is money!  :-)

THANKS!
