How to connect two different confluence(server) to workplace search?

I have two different confluence(server) with different IP address. After I configured confluence(server) in workplace search, the base URL of source setting is fixed. How can I add a different confluence server to the source?

Multiple Confluence Server instances are not currently supported in Workplace Search. If you have a support relationship with Elastic though, it would be great if you'd file an Enhancement Request. Make sure to explain your usecase - you're the first I've heard who has had more than one Confluence Server for their organization.

Hello Sean,
I see. Thank you very much for your explanation.
