Excel 2007 :: VBA - Insert Missing Columns In A Series

I am currently using MS Excel 2007. Is there a way in VBA to automatically insert missing columns based on a defined series or range of values?

For example, we have a report that displays columns of: Year 2004 to Year 2012 per column (9 columns in total).
Sometimes, it displays missing a year or years (thus; our report has less columns). For example, it only shows 2008 to 2012 (missing 2004 to 2007). At times, it misses some years in between. What we do is manually add those missing years by manually inserting columns then inputting the missing year as their column headers.

Is it posisble for VBA to check if the columns contain all of the defined Year range (for example, you've initially defined: Year 2004 to Year 2012)? Afterwards, all missing columns are automoatically inserted (in chronological order or based on your defined values or range).
