Loading a capacitor symbol directly from Pcbnew into the Footprint Editor, changing 2 pads and putting it back in Pcbnew takes about 2 minutes. Putting it in a custom library also takes a minute or 2.
Such changes are really much easier to do then trying to find something on internet somewhere, and even if you’ve found a footprint on Internet, you’ll still have to do the library thing in KiCad.
The first time you manage your custom footprints in a custom library it takes a bit of time, but after that it’s easier and you have a higher chance of succeeding compared to finding something on the 'net. (Except for really complicated footprints).
