Variance Report with Multiple Fields

Hi all,

First time poster here.  I'm usually able to find most of the solutions within the community, but I had no luck with this one.  Hoping someone might be able to help.

I'm trying to create a dashboard where the users will navigate to a report and populate records with the fields:
   Region (East, West, Central, etc)
   Event Information (description of the event)
   Subcategory (Charity, Sponsorship, Travel, Conferences, etc.)
   Year (2018, 2019, 2020...)
   Spend (the cost incurred)

A record would look something like this.
Year / Region / Event / Subcategory / Spend
2018 / East Coast / Quick Base Conference / Events / $2,000

The end result would be to have reports displayed something similar to the image below:
Each of region reports would then roll up to a summary table.

Any help would be greatly appreciated.

Thanks!
