Procurement dashboard - Monthly vision

Hello, I'm building a procurement dashboard report in a monthly vision and would like to have some support / tips here:

1. How to save this Canvas format file to each time that i create a new report (Jan / Feb / Mar) I wouldn't need to use grey background color, title report with size letter 30 Bold.... »» (POSSIBLE SOLUTION: maybe a Bookmark function would solve my issue?)
2. How is it possible when I insert a new graphic/table the starting format cames already with my background format and the visual border already with rounded corners?

3. Line and Stacked Column chart

i) this graphic represents my positive (green tables) and negative (red tables) price impact ( budget - actual price)

ii) if my first positive impact is an article belongs to the "Type C" i would like to see on stacked column the "Type C" global impact (how to do it?)

iii) I have a table that shows me SALES info and PURCHASING info regarding the same site. Is that possible to add a column on this dashboard that gives me the % between this 2 columns? 

Anonymous are you able to suport?
