The 'types' of slide you often use should be added to the 'Slide Library', so you can add a slide, which is ready to be populated with data, directly to the presentation.
Create a Slide Library
Create a presentation containing the slides you often use, and click 'Add Slides -> From the Slide Library'. The Slide Library will appear in a Pane on the right. Click 'Change to another presentation' and choose your own presentation containing the often used slides.
Insert Slide(s) from the Slide Library
Click 'Add Slides -> From the Slide Library' in the OfficeReports ribbon tab and the Slide Library will appear in a Pane on the right. Select the slide(s) you need and click 'Add Selected Slides'. In the same way you can insert slides from other presentations.
