Can a text clip be one use?

I am new, so I wish know if text clip can be independent with each other. For example, I am making dialog, I dont want to have hundreds text clip, just want one text clip having its own content (with one use).

You can have as many title clips as you want. Just keep in mind that you can’t display lines independently. So if you want only one title clip for the dialog and display certain sections at different times you need to use alpha shapes or the rotoscoping effects to do that
