Reddit reviews Genovation 0405009012 1X1 RELEGENDABLE CHERRY KEYCAP GRAY BASE with CLEAR LENS FOR KEYPAD

You won't find anything for the bottom row since nobody but corsair uses that bottom row (that I know of).

Also, what do you mean by macro keycaps? If you want keycaps that say whatever you want, the easiest way would be to get these relegendable keycaps

However, if you want something that is a bit higher quality, you can make your own keycaps over at WASD Keyboards.
