Wordpress - Bookly plugin - Per service payment setting

Wordpress plugin "Bookly" has a global "SETTINGS -> Payments" area where you can set one or more payment types (ie Paypal, Stripe) and enable or disable those payment methods. The same plugin "Bookly" allows you to create different "Services", but it doesn't allow to disable or enable the above payment methods. Thus, on the front, it will always show all the available (and setup) payment methods. Needed modification on backend: On create and edit service functionality, we need to be able to check one ore more payment methods. The choice should. be only among the ones setup and enabled in the global settings. Needed modification on frontend: The payment methods available in the frontend for the user should be only the ones selected in the service setup modal and also available in the plugin global settings. Important note: You can edit core Bookly files and database tables to achieve this.
