Grouping Rows

[bonnepoutine]

Hi,

I would like to group rows in excel into groups of 3, ex: Client ABC would be on line 3, 4 and 5. Each row would contain different information about the customer. This worksheet would be used by different people and I would like them to be able to sort the list but have (line 3,4 and 5) stay grouped together even in the sort or do an auto-filter. Is this possible ?

Thanks,
