I don't think this is the best way to do this, but recently I was looking to produce a similar result and this is what I did...
I set a field in my interviews to segment them the way I wanted to (in my case, persona type, in yours study type).
I opened a canvas and added highlights filtered by the persona type + pain points (in your case, your study type field and a tag or tags).
Added all of those highlights to an insight. Then opened the insight and used the chat that's specific to the insight.
This is pretty round about, but worked well!
