Customizable prompts for 'Tags > Add Chat Suggestions to Documents'?

Question/suggestion to the DT devs:

I have different groups and other items for which I’d like to add a Smart Rule that adds AI-derived tags (using ‘Tags > Add Chat Suggestions to Documents’). However, there are different domains that I want better coverage of for different groups, so that it would be very valuable to be able to:

(1) Provide a custom prompt (or better, a prompt template) to send to the LLM along with the document as context, so as to obtain more relevant tags

(2) It would also be very helpful for specialized domains to specify the LLM model (such as use model ‘x’ instead of default if available)

Wondering if others would find either of these useful as well?

You could already use the Chat - Query action of smart rules and batch processing for your own prompts and different models.
