[Feature Request] Add option to prefix URLs with current site's base URL

[benface]

It's nice that relative URLs and aliases are supported, but it would be even better if relative URLs worked out of the box without needing to have an alias for the base URL. For instance, let's say I am in a multisite setup and I have a site with the base URL @web/en/ which resolves to https://my-site.com/en/. The way it is now, if I want to enter a relative URL with this plugin, I would have to do it like this: @web/en/my-page. It would be nice if there was an option that allowed us to simply enter my-page in the URL field, and it would render the full URL on the front-end, as if we did this in Twig: {{ url('my-page') }}.
