This would be useful for managing DOIs; DOIs may be imported with no linking prefix or with an out-dated linking prefix and may also pick up unwanted information such as a proxy component to links. Currently bulk edit allows for the removal of outdated and unwanted elements with confidence. This then leaves a basic DOI. A 'starts with' bulk edit option would make it easier to add in the correct prefix only where it is wanted.

This is preferable to using a referencing style to add in the prefix (EG APA 7th - Sentence Casing, DOI: https://doi.org/) as this does not generate fully functioning links.
