Maintaining multiple sheets with the same format

I created a tracker that I then created 20 copies of and each one is used by a different team. The sheets all have the same workflows/conditional formatting. The business owner keeps wanting to make tweaks to the sheet (like to add a column or something) and it is very time consuming to do that to each individual sheet. Is there anyway to have a master template so that when I add a column to the master template, all of the individual sheets get the column added to them to?
