I have a large google document I'm working on. There is the same text there that used in many places. It is changed sometimes as the document evolves. I'd like to have some way to change it automatically. I declare a variable some_variable in some document metadata layer with the value of "text". Then everywhere this variable is inserted as ${some_variable} it will be automatically replaced with "text". In this case I won't have to go over and do it manually. I believe this feature is available in MS-Word. Is it possible to do the same in google-docs.
I've tried Doc Variables plug-in. However, it seem to be able to only replace variables with values once.
