How to "squish" a solid, smoothly?

I apologize in advance, I am not sure what the correct term would be. If I have a solid cylinder that I created and I want to flatten/squish one end to match the pendant. How do I smoothly transition from flattened to not flattened. If I scale just the edges and face of the end, it doesn’t look right. Not sure if there is a tool or extension for something like this? Hopefully this makes sense. Thanks :slight_smile:
