PPT Productivity's Color Palette Toolbar for PowerPoint has a setting option that lets you update both the fill and border / outline of a shape in PowerPoint in a single click.

By default in PowerPoint, changing a fill color only changes the internal color of a shape - you need to change the outline color separately. PPT Productivity enables you to override this. Simply click the gear icon at the bottom of the PPT Productivity Color Toolbar and select the option Set Line with Fill.

If you apply this setting, each time you click the Fill icons on the Color toolbar, both fill and border colors of your selected shape(s) will be set to the selected fill color. Helpful shortcut if your preference is matching shape fill and border colors.
