Create custom new page in ECC with custom data set - not extending an existing page or data set

There is a business need to create a new dashboard in ECC. This dashboard will source data from a custom data set.

This dataset will encompass data from multiple standard and custom Oracle EBS tables.

Please bear in mind that this is not an extension of an existing dashboard or an existing data set.

From a high level, is this possible?

Reading thru the documentation, they seem to allude to extending an existing dashboard or an existing data set.

Perhaps I am wrong in my understanding.

Any insight would be helpful.

Thank you.
