If I understand your question correctly, the answer is simple.
NO
- If you use Subtitles you can not change the size and location.
Therefore, the easiest way would be to:
Take any text that resembles the type of text you want from 'Title Room' - drag it to the timeline where you want it to appear - click modify and type the text you want (and make the changes you wish ) - click on 'Save'. Now you have the text without having made a template.
Only if you click 'Save As' creates a template.
