Inserting New Columns and copying formatting

I have a sheet where I need to add some more columns in the middle, however when I go to insert the columns, the formatting and coloring of the cells follows the columns at the end of the sheet, rather than those on either side of it.  Does anyone know how to make it so that when you hit "Insert Column Right" or Insert Column Left, it will copy the formatting of the cell you click on?  This seems like a basic detail to overlook.
