I need to run a report that filters down to just my inactive customers and see their sales for the year prior.  

One of our customers switched ownership and renamed with something very similar.  They have 9 locations.  To avoid confusion, we needed to make the old customer inactive.  But now I would like to do a side by side comparison of last year's revenue to this with the old customer name and the current customer name, but I am not able to select the inactive customers on the filter list because they do not appear there.  
I cannot make them active again, so this is not an option.  

How to I make them appear as a selection under filter on my sales by class summary/detail report? I am using Quickbooks online.
