Azure Policy - Seeking Guidance: Adding "Destination Table" to Built-In Azure Policy

Hi Team,

I am sharing the existing Built-In Azure Policy that previously sent logs to Log Analytics Workspace. However, it currently lacks the option to choose "Destination Table" with selections such as "Azure Diagnostics" or "Resource Specific."

I would like to include this option in the policy. Could you please advise on how to achieve this?

Built-in Policy Name : 

Enable logging by category group for Application gateways (microsoft.network/applicationgateways) to Log Analytics
