Is there a way to format the EnumLookups so that properties with the same values in the Enumlookups don't need to be repeated? For example: If I have three custom properties that all require a Yes or No answer. Can I group them together in the enumlookup rather than having seperate Yes or No lists for each property?
I'm not aware of any way to do that since each group of lookup values is categorized based on catalog type, so it would seem that both the Save operation (from the Definition Editor) and each tool's read mechanism is involved.
If this is something important to you I would recommend logging a Service Request with support so that an Enhancement request can be filed on your behalf.
