Powerpoint macro to always bring an object to front on the current slide

I have a pptx where I want a certain object (referenced by name) to always show on top of all other objects.
I'm thinking using a Macro to re-arrange the object whenever there's a change on the slide (in editor mode)

I have managed to use the
ActivePresentation.Slides(slide).Shapes("Top-Logo-Pink").ZOrder (msoBringToFront)
function, but I need hee following requirements to be working:
- automatic invocation of the macro upon changes in the PPTX
- must run on any slide where the object with the name "Top-Logo_Pink" exists
