Automatically Insert Static Date In Different Columns Of Same Row

I recently found on this site the macro to auto insert a static date in one column when an entry was made in the previous column.

What I have in my spreadsheet and what I would like to be able to do is if I select a particular Order Status from a drop down list, that it auto inserts the date into the respective columns.

Column F contains the various Order Status indicators ie Order Submitted, PO Raised, Delivered, and Invoice Received.
The date columns that I would like populated and which correspond to those status indicators (in order) are Column G, Column I, Column L, and Column K.
So if I pick Order Submitted, the status date should be auto populated in Column G. If I pick PO Raised, the status date should be auto populated in Column I etc.
