Switch between heat and cool on custom climate

With the seasons changing, figured id set an ease of life feature request.

Most of our rooms are climate controled individually (with window AC units or space heater style heaters.

Feature request would be the option to change a custom climate (thermostat) entity from ac_mode from true to false and back through the button created in lovelace, or via the entity itself.
(would be awesome if included was an assignable power switch based on ac_mode (so, if i have an AC unit AND a heat unit plugged into 2 different smart switches, we could change from AC to HEAT mode and have the appropriate switch linked automagically.
