I'm not sure on the desired behaviour, and whether this is actually a bug.

I would like to have a "Project" prompt then have a specific "Assistant" prompt that adds to it.

For an example if Project is "Sales" then the Assistant may be "Messaging".

I looked in the knowledge base for this case, and I was unable to find anything. It's also not clear whether it follows Project System Prompt or the Assistant Prompt.

System Instruction says "Project" but then I have the Assistant activated in bottom toolbar with no feedback on which wins. From output, looks to be the Project Prompt.
