More possibilites to apply templates

For us it would be of great help if templates could be used more for formatting in more ways.

If you for example have ten slides with text and want to change the font, as it is now you have to change every slide one by one.

Another example: we have two churches, one with LCD screens and one where we use a projector. The text needs to be of different size depending on where the service is. Therefore, it would be fantastic if a template could be applied on a cue list.
