New Fields in vcard_search

[elenaapp]

Hello, I need to add additional fields such as "Role," "Note," "Prod," and "Agent" to the vcard_search table. I am looking for ways to implement these changes without modifying the existing database and codebase to prevent complications with future updates. Could you provide any guidance or suggest potential solutions that would allow for these enhancements while preserving the integrity of the current system?
Thank you for help.
