Pyxel Edit doesn't support indexed color modes I'm afraid, but you can achieve what you want using Replace color for palette swatches. You can quickly access it by holding Shift and double clicking a swatch, or right clicking and choosing Replace color.
There is some glitchyness with this feature in the current release, colors don't update when using some of the controls, but this has been fixed in the upcoming version.
