Perfect for an "include" type of function

I created two columns in my pages and on several of them, the second column was occupied by what appears to be a sidebar, but is actually all part of the same page. Using a sidebar was not an option for me, and I had wished I could use a simple include instead, which also wasn’t an option, so this was the perfect solution! Now if I have to update that content I only have to do it in one place rather than on several pages. Thanks!!!
