Designing templates with PGL

I am trying to figure out how to design my templates around my PGL. Before, Iassumed my PGL was always 0.5' below the median, and I showed all grass medians as being 2% crowned. I know this is incorrect, because the PGL location varies throughout the project. The only sections that the medians aren't crowned is where there is turn-lane medians. So, I would like my templates to be based on where my PGL is (can be seen with the PAVE and ALIGN files). I would like a one-template-fits all approach if possible. I attached my .ITL file, which the main template I've been using is called "FM 548 ProposedCondensed". I also attached typical section that represents generally what a turn-lane median section looks like.
