Is there a possibility to create scripted data source and feed it to Reports?

[rubesh_u]

I want to build Report with the result of a aggregated table but I don't want to create this custom table 

Field Name Type Description

u_agent	Reference → User	Assigned agent
u_date	Date	working day of the agent
u_case_count	Integer	Number of cases for that day

This is the report that I want to achieve

I'm using Advanced Dashboard and creating the reports with UI Builder
