PowerPoint Hybrid Formatting
PowerPoint comes with a set of ready made designs and templates that would usually cater to your need. This is what makes PowerPoint easy and friendly to use. With PowerPoint 2007 and newer versions, shapes, texts and smartarts now have more formatting sets (color, fonts, effects and etc) than you would ever get to use. However, there would be a time where you will be thinking of mixing these formatting to suit your need. Unfortunately, changing the design means reformatting the entire presentation slides, where all the shapes, texts and smartarts would be affected.
There's a way to achieve hybrid formatting. First, for those who are unaware of the design and formatting sets, open up PowerPoint, then click on the Design tab. Under Design, you will see various formatting such as Colors, Fonts, Effects, Background Styles and many more. These features are available to help you format your presentation without the need to edit them manually, such as assigning a particular color to all the shapes or a particular font to all the texts. In short, it makes thing much easier. A combination of these formattings allow you to create tons of variations to each presentation. Technically, with some tweaking, you could say that no two presentation will be the exact replica.
Now, in order to achieve hybrid formatting, open up a blank presentation. Next, create the object that you wish to have (e.g. text, shape, smartart, chart etc). Give it the formatting of your choice. Then, right click on it and select Copy. Go back to your initial presentation and paste the object onto a slide. You will see that the object changes to the formatting based on the initial presentation. To switch it back to the new formatting you have created, click on the 'Paste Options' icon beside the object and select 'Keep Source Formatting'. You may also wish to save the new formatting by saving it as a presentation file for future use. The advantage of this hybrid formatting allows you to mix various preset designs made available in PowerPoint. However, do keep in mind that by doing so, these hybrid formatted objects will stick to their own formatting, thus they will remain unchanged when you attempt to change the design 'globally'.
