I understand that the decision was made to give the suppliers who have been around longer a higher spot on the list. But the list is just getting too long. 74 suppliers!
I think that the section should be grouped by country or region, such as:
Northeast US
Southeast US
Midwest US
Northwest US
Southwest US
Canada
Western Europe
China
and so forth
Keep the seniority order in place, just separate suppliers by country/region so there's not a awkwardly long single list. You will get some level of organization while still maintaining preferable placement for those suppliers who have came on first.
