Blueprint - Update a sheet summary column for all projects

Hi, I am using blueprint to manage over 600+ projects. It has come to my attention that the working team wants to add 10 new data points. What I have been doing is adding those 10 new data points in a "Site detail & metric" sheet for each project, then going into the blueprint to add the new columns. I know it won't automatically link for previous projects in the portfolio summary sheet, but is there a way to add the 10 data points to the 600+ sheets without manually going into each one?
