Editable Templates for Slides in presentations

Today there are only 3 types of slides and it is not possible to create a customized template, with different text boxes, fonts, etc. This would be similar to what is currently available for song lyrics.
One alternative would be to enable duplication of an existing presentation, that would work as a template. 

Yes, this is possible.  In the slide editor, right click on a thumbnail you would like to use as a template and select "Save as Template".  Next time you create a new slide, you will see that template as an option.

Thank you! I missed this one... Just tested and works perfectly.

The only issue we have with this feature is that if you just click the duplicate button on the right side, it doesn't hold the template to paste over or retype.
