[Feature Request] Allow wildcard for the URLs that have only the domain

### Summary:
Currently, if a connection is attempted to something like `domain.com`, then the destination dropdown has only the `domain.com` and its IP addresses/subnets.
If the destination is `www.domain.com`, then the dropdown has `www.domain.com` and `*.domain.com`.
Could the same be used for the 1st scenario as well? The rationale for this is that later on requests for other subdomains are likely to follow, and the user is likely to need the wildcard anyway.

Thanks!
