Adding a "Set Fan Hold" action?

Hi,

I am not sure how big a request this is:

The ego be app as a screen that allows me to run the fans for 15 minutes 30 minutes, 45 minutes, etc.

This feature is very wife friendly during the winter, as it cools off the bedrooms without turning the air conditioners on (we have steam radiators for heat on a separate thermostat).

How challenging would it be for you to add (or possibly for me to add) functionality to set fan hold to one hour?

Create an issue in GitHub and I'll take a look.
