I actually save a csl (client specific letter) for each client.  I always go to it (edit) and preview before I actually even e-file the return.  1) it alerts me to some things i might have overlooked during my reiview (those triggers are sometimes helpful), and 2) it allows me to address aesthetic issues like you mentioned.

I can usually fix all of those issues thru adding or deleting lines above/and or below the date line on the 1st page.
