Consistency Within Graph Labels

I have a customer that is running into a limitation with reports and colors associated with those reports. The customer has two reports on one dashboard that are using the same "By" Fields in the report. By using the same logic in the report, the customer expects that "account name" will be the same color for the same customer in the report (i.e. ABC company shows up red in both report, XYZ company shows up as blue in both reports). 





It is my understanding that we now have the ability to be able to custom color these, however, he can't custom map thousands of customers to custom colors for reporting. Are there any alternatives/workarounds? If not can we take that as an enhancement request? 





I have a screenshot which I can share privately, I don't want to post publicly because I (obviously) cannot redact the "Account Name" from my screenshot. 
This would be a very well received change!
