Hi Tom
I have been informed that with the new Support Online roll out this option was removed, so right now a user can only find solutions for ALL components of a product, or a single component.
It is however planned to bring back the capability to individually select each component but there is still no ETA as of today.
If this has answered your question would you be able to mark it as correct? This will update the question allowing others with similar questions know that you have received a helpful answer.
Thanks,
Elke
