Currently, there is no shortcut link feature on Bitbucket cloud repositories. However, there is one exists on Bitbucket Server
The shortcut is a link to a site outside of Bitbucket cloud instance. The feature will allow users to quickly navigate to other links outside their instance. For e.g. the links could be used to reach the applications integrated with the repository.
Why this is important
Similar functionality is available on Bitbucket server, it would be good to have the same on Bitbucket Cloud for users migrating to cloud.
