I have a spreadsheet with part numbers and associated cycle times based on
part families (similar products grouped with same cycle time):

part num ct
D26MF 5
D26MPL 5
D26MPL 15
D26MPR 15
D26MBA 8
D26MD20 8

When the cycle times change from process improvements I need to lookup up
the product families and change the cycle times all at once rather than one
by one. Is there a function for this?
