VS 2012 [RESOLVED] Resume from empty primary key

Hi Guys!

I read at many places that it is impossible while autoincrement is on but I'll give it another shot.
How to:
PKs 1,2,3,4
After deleting 2, 4
I don't want it to continue like 1,3,5,6...
I want to first fill the 2 and 4, then continue...

Any advice?
