Copy/Paste textboxes into alternate rows

In the attached sample file, I show the basic page layout where I am trying to add an empty textbox into the bottom portion of a cell in every other line which would then be indexed based on a cell in another worksheet. I found that I can copy and Paste Special (as a GIF) for each line, but this involves manually dragging the box into position.

For only a few cells, this wouldn’t be a problem, but I have about 600 rows (1200 in all but I need to skip every other row). I searched the net and this forum’s archives but can’t find a solution to match or get close enough to my situation for me to experiment. Any suggestions?
