Rotating and positioning arrows inside TileList

Alright, I thought this was going to be an easy task since I have a few years of experience with Flash, but I realize that I’m just going crazy trying to fix this so I need help.

How do I position the arrows I’ve placed inside the TileList so that they point from the center of the TileList object and towards the border of the TileList object?

Currently, they’re positioned in the top-left, and they points toward the expected direction. Because they’re positioned incorrectly, it doesn’t look good (See submitted files)

I hope you guys have more experience with TileLists than I do.
