Docker Container Template: Add reverse proxy URL to "WebUI"

In the Docker container template, I would like to have a feature that will let me define/configure a WebUI link to the reverse proxy for the container.

I have a WebUI configuration for local connection.

I have a WebUI configuration for Tailscale (but it won't let change it, and uses the Tailnet domain, not my reverse proxy).

I need to have a WebUI for my reverse proxy. And I want this to show on the container menu so it is easy to open the reverse proxy link.

Thank you.
