Is it possible to have one script for multiple spreadsheets?

Question

I have one master spreadsheet and a number of copies. This master spreadsheet uses some scripting.

Is it possible to link all the copies of this master spreadsheet

Answer 1

The solution I put in place in this context was to have a Google Site, where the Master Script is embedded, and where the Spreadsheet is embedded too

Then, the script, refering to a dedicated spreadsheet, looks for the Google Site Page's name, looks in the Master spreadsheet and get the ID of the spreadsheet which is embedded in the Page.
