This feature would be extremely useful!!!
Squarespace mods, please listen!!!!!
It is November 2021 and we still cannot copy section blocks from one page to another page.
I used the list block feature to create a 4x4 list of images and text that I want to use on 8 pages but I will have to build these all manually. This is a lot of work for a basic feature. At the very least, we should be able to save our own content blocks in the Section Library.
