What would be a standard indicator for a selection set to default?

I have a table with different user options.

These options are either coming from a base template (Standard), a customized base template (Custom), or a customized base template that has not yet been published/finalized (Draft).

From these options, the user can select one to set as a default using an option from the ellipsis menu under each row. This default will then be used as the default rate for them.

What is the best way to indicate that this rate is their default? A star icon next to the rate name? A left border? Any other ideas?

Note that there can only be one default rate.
