Alerts for embedded dashboards

We mostly use dashboards as embeds in a separate application. We want to use alerts but notice the links in the alert / subscription emails always drive the user back to the main instance. Is it possible to customize the url for those alerts (i.e. "myportal.com/metabasedashboard" instead of "metabaseinstance.com/metabasedashboard"). Most of the consumers of the dashboards we build do not have access to the main instance so the links always drive them to a dead end.

Thanks in advance!

Unfortunately you can’t, but if users can’t get into the instance they’ll get into the login page
