Fix Gaps in Dates

Hello,

I have the attached report which shows begin and end dates in column I and J however there are gaps in dates when you look at the lines for the same person (DBA column) in the rows below. I am trying to see if there is a quick way to have a macro insert a line between each row that has a gap and fixing the gap issue with the new row. It would also have to do this by Co in column A so that when the Co changes the macro starts fresh with the date gap test. Thanks in advance!
