Hi @Jason_Morris and welcome to the forum!
Unfortunately, Universal Reporting only currently allows you to create dashboards with task data. Hopefully in a future release we will be able to report against project data as well.
One way that I am able to achieve what you are describing is through the Google Sheets integration - Google Sheets + Asana: Create custom reporting • Asana
Once you have a Portfolio synced to Google Sheets you can do a lot of custom charting or introduce pivot tables. You might find this reply (or thread) interesting: Showing sum of project's numeric field (costs etc.) in Portfolios - #3 by LEGGO
