Bulk Import Images Into a Style?

I feel like I must be missing something easy here. I have been on a hunt for the National Park Service symbols or something similar for use (and more importantly, reuse). Posted looking for it here. I never got a response so I thought, ok, I'll just go get the SVGs from the the NPS' source, I'll just make my own SLYX file and upload them all. Now I'll have a style that I can reuse in other projects. It appears that that there is is no way to bulk upload images to a Style? It actually appears I can't even add them one at a time, it looks I have to first use them in a layer and then add them to the style? I'm sure I must be missing something......

Is there any solution for bulk import PNGs into the ArcGIS Pro styles (.stylx)?

I have over 300 icons and I’m trying to avoid adding them one by one and manually setting each to a Picture Marker.

I’m using ArcGIS Pro 3.6.0.

I found this other community post that was very helpful. With the code provided I managed to use ArcPy to load the PNG files into a .stylx file.
