Rollup - One column with multiple sources

Hi all,

I find myself working on things a lot as I understand Airtable.

I am trying to do a budget spending, and I have multiple school locations showing the month-to-date spending.

I then wanted a table which shows all the schools.

The issue is I can only link one table.

I want to be able to link to multiple. 

So I can have all the budgets in one view.

Thanks,

Judd
