Sorting

Hi I have some attached data that I have sorted by the "Day" header Column L. I would like it to, when there is a duplicate "Customer ID" Column A, to group all the Customer Id's (rows) together so that it would show them one underneath eachother as per the After worksheet. But still keeping the non duplicated rows in the orginal date order. Your help would be great appreciated.

Hi I am new to this, are you directing me somewhere ?
