Keep Your Text Styling when Copy and Pasting Object Style
Don't override your typography
Learn how to quickly copy and paste style for PowerPoint objects, like can with the formatting painter, without losing your text formatting. This saves you from having to go back and correct font weights, bullets, font sizes and other styling you may wish to keep.
For an even faster method, rather than duplicating the object, you can also copy the text before applying the new object style but my preference is to have the duplicate object to help doublecheck that all the text formatted correctly.
