Filtering Resource LOV in Service Object-Scheduling information Screen Based on Custom Attribute

Hi ,

I have created a custom attribute on the Resource entity (e.g., a boolean flag to identify specific resources).

Now, I need to filter the Resource ID LOV in the Service Object screen so that it only displays resources where this custom attribute is set to TRUE.

This is the LOV where i need to filter based on my custom attribute
 

Is there any way to modify or extend the LOV to include this custom attribute in the filter?
Has anyone implemented a similar requirement?

Any guidance would be appreciated.

Thanks in advance!
