Sound equalizer in rekordbox

I've seen here on the forum that there are more people who have addressed this issue - rekordbox having an equalizer. I'm not a professional DJ and professionals probably won't have this need. I use the FLX-4 and it has bass, treble and mid buttons. But these are designed to be used not for "tuning" the sound but for mixing.
It turns out that sometimes the PA doesn't allow us to make the sound adjustments we want. Sometimes we want to improve the sound, for various reasons - because the room is not acoustically good, etc.
I don't always mix dance music, sometimes I mix jazz, and "lounge", and sometimes even songs with high quality recordings (audiophile) and that give more precise adjustments to the sound and it is not possible.
Anything like a 10-band equalizer would suffice, with the option to use it or not and with the option to have half a dozen presets.
Pionner DJ, think about it, it's something you can easily add to Rekordbox.
