Using unstable_dev is there a way to pass and get responses to various baseurls?

Using unstable_dev is there a way to pass urls with different baseurls(what would normally be part of the routes section of the worker toml) instead of https://ip:port ? ie: I have a rule that redirects a route called https://example.com/test, can I fetch that using worker.fetch()?
Currently the baseurl gets stripped and it comes through as https://ip:site/test
