How to break the associativity of a balloon callout from the parts list, so that text can be edited/modified and will not update according to the parts list.
Solution
1. With the Balloon dialog open, select the 'Select Terminating Object' option under the Leader group of the dialog.
2. Turn off the 'Enable Snap Point' option in the slim ribbon bar.
3. Place your cursor at the desired location and place the balloon (it may be needed to zoom in on the area).
4. The balloon is not associated to anything, and the text can now be edited and will not update with the parts list.
