My "workaround" has been to go through my customer list (one time) and label customer type:

Name: A-H
Name I-O

Name ame P-Z

This will then cause you to run it. Obviously you will have to clear "customer type" 

Obviously this is not a solution, nor is it effective. I have to limp along what is supposed to be enterprise grade software...

Silly that we have to make this company work to earn it's money. What a shame. /s
