At present there are two primary entry points to editing knowledge:
Through the left-hand "Knowledge" navigation link.
Via the topic links on the assistant QnA page.
I have a number of assistants, each with their own topics, and when I access the knowledge from one of my assistant's QnA skill I would like to:
only see knowledge linked to my assistant
be able to use the Query tool and query only the knowledge my assistant has access to; without this it's difficult to debug / test my assistant's knowledge without the results being polluted from unrelated (and not linked) topics.
Related to this, it causes confusion and shows topics I'm not interested in when I click the Save button - the filter is removed.
