Bitwig EQ vs Toonebooster EQ4

[Boudin]

I use tonebooster EQ4 because of the flat top EQ curves, great for making fat and round kick drums without adding too many subs to the mix. in my opinion the sound is better than the sound I get out of a pultec EQ plugin (60 or 100 hz), like the native bitwig one.
How can I emulate this feature in Bitwig as bell EQ has no flat top shape ? I can only adjust the resonance but it changes only the base of the curve, not the top.
Tone booster has also a drive fonction to add a nice analogue distortion to the sound.
Note : I produce techno music, so the kick drum is obviously the most important audio part in the mix !

If you are talking about Butterworth, they are either available or they aren't...
