Can I use a global OAuth redirect URI across multiple Salesforce orgs?

We’re developing an AppExchange app that integrates Salesforce with an external system using OAuth 2.0 

Each Salesforce org generates its own unique callback URL, which currently needs to be registered in the external system's OAuth client config. 

Question: Is there any way to use a single global/static redirect URI (or wildcard) across all Salesforce orgs, so customers don’t have to register their org-specific callback URLs individually? 

Looking for best practices or workarounds used in multi-tenant AppExchange apps. 

Thank you!
