Custom Order Template VBA or Macro

I am trying to write a formula whether it be in VBA or a Macro that will do the following.
In cell A7 and A10 there are validation boxes that drop down with a list of items that can be selected.
We want the user to be able to add multiple items under each month but keep the list to only what is needed. Therefor the function I am trying to get is once cell A7 has a selction or isnot blank or is greater than 0 we want to add a line directly below it with all the same functionality as line 7. Everything else will shift down and maintain the same functionality.

I have a attached a sample workbook... Can this be done and if so any help would be greatly appriciated! Thanks RAH
