Pricing calculator

Alright, so I'm trying to create a pricing calculator/pricing report generator to use in a cabinet shop.

I did all the logic and such, and the calculator works. I have a few other things that I would need it to be able to do though, I'll do my best to explain.

So basically, we price each room of a job separately.

So, I need to be able to somehow do each room as a separate submission (or maybe not, I'm open to ideas here) and somehow have the rooms all tied to one job, then, I want to be able to print a report, and have all the rooms on the job listed with the specific items and such per room, and then a total price of all the rooms at the bottom of the report. Hopefully that kinda makes sense, I'm not sure if this is possible.

Here is a photo of the calculator form, I would need to fill this out for each room of the job.
