Layout grids Aperture Photo Books

I am attempting to make sure all of my photo boxes and text boxes are consistent throughout a book I am designing.

I can not seem to find any feature that will allow me to precisely create and place images, text on pages.

There is a very basic center tool and outside margin tool -are there more tools somewhere I am missing or do they not exist?

If they don't Apple please add them. How can you have a professional tool without this basic function.

Also can you link text boxes to flow text?

Any advice as to how others have dealt with this.

Thank you
