swagger microservice integration for body schema

Question

we have schemas in our swaggers: like this:

if we have many microservices and use them in many other API routes in another service.

when s.th change we need to change all schemas in all of our repositories

EXAMPLE:

I have this microservice:

survey.com/api/docs

and I want to use json sample shema in many other microservice like this:

app1.com/api/docs

and

app2.com/api/docs

and

app3.com/api/docs

when we add a property to my main microservice and schema changed I should refactor all my other schemas in other git repositories.

is there any way to map one route to another swagger document to read these schemas from there?

is there any way to manage these changes? by versioning?

if app1 and app2 and app3 use one route with schema and source API route schema of survey.com changed we should modify all our swagger documentation
