Inquiry regarding data granularity and merging capabilities for Consumer Edge datasets

I noticed that the current data files, such as "Brand & Demographic Cohort" and "Brand & Geography Cohort," appear to be pre-aggregated. Due to the lack of common identifiers, I have been unable to merge these tables to analyze the interaction between demographic and geographic variables.

Could you clarify if these datasets are designed to be mutually exclusive, or if there is a specific method to link them?

Additionally, I have observed in other research that Consumer Edge data is sometimes used at a much more granular level, specifically at the weekly cohort or even transaction/row level.

Could you please advise if it is possible to request access to this more granular, disaggregated data? Access to the raw panel data would solve the merging issue and is critical for the elasticity modeling I plan to conduct.

Thank you for your assistance.
