Looking for a script that will allow the following

I have to write a newsletter every month.

I want to have a project called “Write letters every month” that repeats on the due date when I have to have my letters in.

But each month, the articles change. In other words, One of the items may be: “Write about racism in America” but then the following month I want to write something else. The problem is that as it is right now, if I set the project to repeat every month, when I check off all the articles that I want to write and the project repeats, it repeats all the “old” article names … Is there any way I can check all those off and then the project repeats but is EMPTY and has the next due date?
