Hybrid Mock Responses

Hello,
I’m just getting started with Stoplight. I’ve been using dynamic mock responses for many of the API test calls my web app is making, but I’m also needing to include hard-coded example responses for certain APIs whose data I need to join with mock data received from other API calls (e.g. one API call to get accounts and a second to get services under each account). When the IDs I would normally use to join these datasets are randomly generated, I can’t perform joins so I have to use static responses. I hate doing this though because I have to manually change those responses whenever I make changes to the model behind them. Is there a ‘hybrid’ solution that I’m not aware of?
Thanks!
