I wrote a little function that creates some menus and registered it with the onOpen() event with my spreadsheet in Google Drive so that the actions are triggered and the menus appear automatically whenever the particular spreadsheet gets opened. But there's a catch. I want this to happen for every single spreadsheet that I will ever have in Google Drive/Docs. Even the ones I create next week. Of course, I don't want to go through the process of registering a trigger for each particular document.
Is there a way to say "hey, every single spreadsheet in my account will have this function triggered on onOpen"? It seems like a highly usefull feature.
If this is not possible, can Zend's GData API for PHP somehow remotely run a script on a spreadsheet? Since all my spreadsheets come from a PHP web app, I could overcome the problem by triggering the execution from PHP.
