Manage oAuth2 and Cookies in a same collection


For now we have 2 ways to access our APIs: oAuth (mobile) or cookies (web).

In Postman we have created 2 collections: one using oAuth and the other one using cookies.

So we have duplicate all APIs in both collections.

Is there a way to have only one collection capable to use oAuth or cookies on demand?

Many thanks for Your help.
