It's doable by a combination of several commands.
1. Be in the zone, and place cursor in the center of the window
2. /itemtarget drop
Will target groundspawn, which has drop in the name.. This seems to be all items for the quests. It will not put the item on your target window but it is targeted.
3. Using Mq2moveutils: /moveto ${ItemTarget.Y} ${ItemTarget.X}
This will move you to the item
4. /look -128
Once at the item, Do /look -128 to look directly down at the ground spawn. It should be very close or fill up the center of the screen
5. /click left
This will click the center of the screen, and pickup the item
