Disable specific custom cells & formulas and/or save them all

Hi,
writing a trigger file, many times it is needed to write some (or many) custom cells & formulas.
When we change to a new trigger file the previous custom cells & formulas are active. I must delete them and write the new ones, and, the next time I will use my previous trigger REWRITE them!!!
It should be very useful to have a "disable" button / custom cell and/or save all of them in a file.

Best Regards,

Theodore
