Hi MS Office World

Does anyone of you know, how to set up a new ribbon tab in Microsoft PowerPoint and import forms, icons etc. so that they can be accessed in a quick and easy manner? I actually know how to set up a new ribbon tab but struggle with linking it e.g. to a local order from where it can import own forms and icons and make them accessible under the ribbon tab. Is there a Add-in that allows this or is this to be done with VBA? Thanks in advance for your help.

Kind wishes

Robin
