you can also just change some variables if you still want the cut in for preg, and edit the receptionist js to chose what visitors can appear.I am looking a bit and I must say that the ccmod is easy to edit:
// These conversions do not apply to 'wanted' visitors
// Chance to convert female spawns to male, 0 to disable
var CCMod_receptionistMorePerverts_femaleConvertChance = 0;
// Chance to convert spawn of non-pervert to pervert, 0 to disable
// Applied after femaleConvertChance so it can change those too
// Most male visitors have a chance to convert on their own if observing lewd actions while waiting in line already
var CCMod_receptionistMorePerverts_extraSpawnChance = 0;
// These conversions do not apply to 'wanted' visitors
// Chance to convert female spawns to male, 0 to disable
var CCMod_receptionistMorePerverts_femaleConvertChance = 1;
// Chance to convert spawn of non-pervert to pervert, 0 to disable
// Applied after femaleConvertChance so it can change those too
// Most male visitors have a chance to convert on their own if observing lewd actions while waiting in line already
var CCMod_receptionistMorePerverts_extraSpawnChance = 1;
so in the receptionist job there are only male perverts
////////////////
// Lose panties easier. Normally requires passives. 1 = 100%
var CCMod_losePantiesEasier_baseChance = 0;
var CCMod_losePantiesEasier_baseChanceWakeUp = 0;
var CCMod_dropPanty_petting = true;
////////////////
// Lose panties easier. Normally requires passives. 1 = 100%
var CCMod_losePantiesEasier_baseChance = 1;
var CCMod_losePantiesEasier_baseChanceWakeUp = 1;
var CCMod_dropPanty_petting = true;
with this one it's always without underwear
// Pregnancy stuff
//////////////////////////////////////////////////////////////
var CCMod_pregModEnabled = true;
// Pregnancy stuff
//////////////////////////////////////////////////////////////
var CCMod_pregModEnabled = false;
with this you disable the pregmod
