I have multiple spreadsheet bound projects, and I want once in a while run all of them together. Is there a possibility to automate this, as I do not want open each project and run it manually. And as I understand I cannot create installable timed triggers, as I have more than 20, and I am not collaborating with anyone.
My vision - is to create a standalone project where I loop through all the projects using their project/script key(id)s. I only do not know if this is possible, and if yes how do I code this - a call of a script knowing its scriptid?
