let's follow up here...
Assuming you take action prior to April 1st, you can place your Extra VAC Days at the beginning or end of an awarded vacation week. Since you were on top of it, and placed your days prior to the start of the next vacation year (April 1st) there is no need for company concurrence!
for that part, how do i add a day at the beginning from my bank? All i want is my vacation to start one day earlier. figure its easier to just confirm it now instead of trying to bid it off since we are buying tickets/hotels.
