Is there any option to do customization on Calendar module to newer version 9+
Requirement : In calendar module > Shared > Userlist > Select Filter user list by team > Users (Select users for calendar display)
User list option in Users (Select users for calendar display) section is should be inalphabetically sorted.
I have tried to achieve this requirement by changing default files. And its working fine as expected. But for upgrade safe need to do our changes in custom directory.
I have made changes to default file and file is modules/Calendar/CalendarDisplay.php
To add Calendar module in studio, we have create studio.php (blank file) file and give permission and repair rebuild the instance. -No Calendar module is displayed on Admin > Studio > Module_List File Path: modules/Calendar/metadata/studio.php
To execute custom file, We have create Calendar module folder on custom directory and copied modules/Calendar/CalendarDisplay.phpfile from default directory to custom directory i.e.custom/modules/Calendar/CalendarDisplay.php-Butcustom/modules/Calendar/CalendarDisplay.phpfile is not executed (We have checked via printing logs to sugarcrm.log file)
