Help with FL Studio Macro Knob values

If anyone uses ableton, you know how you can map a parameter to macro in a rack, and then click on the “map” button of the rack and change the overall values for each parameter.

For instance if you map a high pass to a macro it will default to going all the way across the filter until u click on the map button and make it so that when the macro is all the way up, the high pass will be only half the way up or whatever u specify, how do i do that in FL? right now when i move the knob all the way to the right the highpass follows but i want it to stop at halfway across the spectrum when the knob is all the way up if that makes sense
