How do I do comparison charts with a group?

How do I do comparison charts with a group?

Is there a way to create on-the-fly group in Zoho analytics and compare the performance of a product/entity against the group?

e.g. In this dashboard - I would like to compare the performance of a given Credit Union to its peers (ideally selected by users or hard-coded)  https://culytics.com/blogs/cu-peer-benchmark. e.g. Performance of a credit union compared to all other in the same asset range and/or state.

How can I achieve that functionality? The underlying data has data for each credit union.

Thanks.
