Hi Eric,
Thanks. I had put the program version that I was using in the subject. This was the first post that I have put into the Q&A so I am not all that familiar with it. So, from what I think your saying (and the lack of feedback from others) - the only option is for me to create my own muntin and re-center and resize it every time I make changes to those windows. (We have over 100 DH windows in this cottage so that is not a convenient task.) We have to have our final window order signed off by Tuesday so I was hoping that I was missing something simple as I would think there would be an option to assign different grills to each sash.
Thanks again,
Will
