Hi.

I have a database (MySQL), but it’s configured with multiple tables from other services.

How can I set a prefix for KanBoard tables to visually separate them?

I don’t see this setting in the configuration file:

`define('DB_RUN_MIGRATIONS', true);`  
`define('DB_DRIVER', 'mysql');`  
`define('DB_USERNAME', '...8');`  
`define('DB_PASSWORD', '...7');`  
`define('DB_HOSTNAME', '....1');`  
`define('DB_NAME', '...8');`  
`define('DB_PORT', null);`  
`define('DB_SSL_KEY', null);`  
`define('DB_SSL_CERT', null);`  
`define('DB_SSL_CA', null);`  
`define('DB_VERIFY_SERVER_CERT', null);`  
`define('DB_TIMEOUT', null);`  
`define('DB_ODBC_DSN', 'kanboard');`

Thank you.
