While it is obvious how to create a custom Component Group to filter by specific attributes, how do you setup a Component Group to search for components that do not have the attribute set or its value has not been entered?
Component Groups has the option "~exists" for filtering Component Groups using Attributes.
The following Component Group definition initially selects all loaded components and then excludes all components that have the part attribute TEST defined:
[ - ] New Component Group
[ - ] Match any of...
[ - ] Exclude...
