Can you use a central HVAC system to control humidity?

So it's that time of year again. 70-75 F and 80% RH outside.

72-74 is fine temperature wise, it's what we leave the thermostat at during the summer but the humidity right now unbearable. If we drop the thermostat down to 70 it will dry up the house before the temperature starts dropping but then once it does it gets kind of cold so you bump it up a bit and it then the humidity starts creeping back.

Is there any thermostat that will control humidity?

You could add a dehumidifier to the system.

Isn't the only difference between an air conditioner and a dehumidifier that the ac pumps the heat out of the building? Is there anyway to achieve the same effect with the current heating and cooling equipment?

When the outside temp is in the 70s or low 80s, the AC run times are to short to dehumidifier the house.
