Hello,
Many thanks for the suggestion, I've now got one on order and will have a go at creating a component for you.

This has now been added via the update system.
Here is an example of it in use.
The multiplexer IC is connected directly to the microcontroller and up to 8 temp/humidity sensors are connected to the CH0-CH7 of the multiplexer.
