Add a back hyperlink in powerpoint

How can i hyperlink to the "previous shown slide" in PowerPoint (2016), like a back button in the web browser. Specifically, i have multiple slides which have hyperlinks on them to go to a particular Appendix slide. I want a hyperlink in that appendix slide to link bank to the referring slide (i.e., the last one that was shown).

Note: This will not be the the slide before it, and it will not be the same slide each time (i.e., since you can reach this appendix slide from several different slides in the power point).

Here is a method to create a "back button" for your powerpoint slide to goto the previously viewed slid:

1. You will first create what you want the button to look like. Either insert an image or shape.
2. Once you have your shape / image selected, click on the Insert ribbon tab. Under the category "Links" you will find an "Action" button. Click that.
3. A dialog appears. Select the "Mouse Click" tab and then click on the "Hyperlink to" radio button. Select the drop down and pick "Last Slide Viewed". Click OK.

Note: The action can be selected to goto a particular slide, the last viewed one, the slide before the one selected, etc.. many options.
