Sensible+Latent+Ideal System settings Humidity Control

Hi,
Hopefully someone can point me in the right direction.
Looking forward to setting what they can be latent (and sensible) loads, using the IdealAirLoads system, i can’t find a way to set the desired Relative Humidity percentage. I see that it is possible to set sensible Heat/Cool Recovery, but this is not the way i’m looking for.
I’m looking for a way like setting the ZoneControl:Humidstat, there you can set directly the HR.
Local codes are asking for this HR percentage as a requirement (using the Ideal System).
Any ideas? Will appreciate your help in this one.
Best,
-A.
