Global Node?

Is there a way to create a text node where the content of that node can be reused in other comps on the same timeline? For example, I want to create many versions of the same spot with different phone numbers in multiple graphics. Can I create a node that when changed in one place, will change in all the other places it is used?

I tried to use Paste Instance, but that only applies in the same comp.

In AfterEffects, I would have placed a text layer in its own comp (called PhoneChanger), and then added that comp to the four other comps. Changing the text in PhoneChange updates the four other comps.

There isn't any global node that cant do this but I can think of 2 ways to get this working, both require some scripting knowledge. The first would be to write a script that can read the text from a file, the second would be to store the text as a parameter in the preferences file and read it using the API.

Krokodove has a "From File" modifier for Text+ that allows you to read lines from a text file.
