I found a bunch of free macros that are all grouped into one GMS file. This offering comes from http://www.grafisin.com/2018/04/free-macro-collections-2018-for.html and might be worth a look. One feature that is very useful is the Duplicate Module. It allows you to duplicate objects or pages with content and however many you want. There are a lot more(I think about 27) of various usefulness depending on your needs.
Just thought I would mention it.

That link goes to a web site with a malicious threat. Nice try.
Anyone that goes to a link posted over 3 years ago is an idiot.
