Include folder of mongoose schemas for different services without manually adding the folder of schemas to each service

Im using sls offline for local development, I tried to use serverless package external so I could have one central location with my schema folder but that was not working. Is there a way in the serverless.yml to just include a folder by path and when you deploy it knows to add that folder but also a way to let serverless offline to know to include it when running sls offline for each respective service?
