By the way this applies to anything that you want to copy attributes too...not limited to text blox.
The trick is to...
...just stretch the first text clip with your new text attributes or settings in the Inspector. Stretch off how many seconds you need for your duplicate, and then slice that much off of the original.
An example would be drag and drop a text clip onto the timeline, dial in all of the Inspector attributes on the text, and then stretch the text clip out 25 seconds long. Now slice at each 5 second mark to make 5 text clips total or 4 copies of the original...all being 5 seconds a piece.
The original text clip when you first drag and drop it on the timeline is 5 seconds long. You can simply double that by stretching, slice, and there is an instant dub.
After you make a duplicate/s with your attributes already therein, then you can stretch each to fit any time frame.
