Convert PDF with comments to a .pptx with comments (not notes) and vice versa?

[Keith29472854ui69]

I'm on a creative team that shares PowerPoint with clients in an interface for fact-checking and review. This interface does not support the clients adding comments to PowerPoint. Still, it allows comment/sticky notes when saved down as a pdf from the user interface (Veeva).

Se can download their comments in a .pdf, yielding them in sticky notes. However, we do all the editing in PowerPoint, where we cannot directly see or respond to the comments.

Can we convert that .pdf with comments/sticky notes into a .pptx with comment bubbles (not notes) to see the person's name and comment in the same program we're making edits in (PowerPoint)?

Finally, can we convert the PowerPoint (with comments between multiple users, not notes) into a PDF with comments as we make slide changes?
