In a Joined Report Identify Unequal Amounts from fields in Different Blocks

Hello Trailblazers, 

I have created a Joined Report with 2 Blocks. 

One block is for Transactions 

One block is for Deposits 

The Joined Report is grouped across Blocks by Account Number. 

I want to identify when the Subtotal for the Amount in the first block is NOT Equal to Subtotal of 'Total Deposit' in the second block. 

Can I create a column in this report that would indicate or raise a flag that these two Subtotals are NOT equal?  Thank you for your help!
