Request Name in Jira service desk to automatically populate in issue custom field

[Abhrajit Sarkar]

Hi,

I am using some request names and groups to configure customer portal, for JIRA Service Desk.
Now, I want the group name and request names to get automatically populated in a cascade select list type custom field, which is created by admin, while creating a service desk request.
The groups and request names are kept same for customer portal and the select list items (for the defined cascade type custom field).
Ho to configure this? Any help please?

Regards,
Abhrajit
