"De-multiplexing" the Arduino DAC output into different signals

Projects General Guidance

I'm trying to build a device that gives voltage to six different outputs, the refresh/frecuency of these signals it's not crititcal, but the voltage precision is. That's why I'm using the two DACs (12 bits) of the arduino DUE.
Is there a way I can increase the number of Analog outputs? Something like a decoder that reads the analog value and outputs this value in one of its outputs depending on the address I'm giving from the arduino and when I send a clock. It has to maintain the analog value.
Does this exist ?

Thanks in advance !

Yes it is called a "sample and hold" circuit. But it is not usual to use it in digital electronics you normally just have more D/A converters.
