Selectable action on tile press

In the editor I can select the action when a tile is pressed, but I have been unable to connect a specific action to that press. For example: I have a temperature selection tile for a convector/heater with the +/- buttons on it, but I would like to switch it on/off (toggle) when that selection tile is pressed which is a different action/automation from the temperature setting.

The action options are predefined and there is a toggle option but it seems to be fixed to the action: homeassistant.toggle and can not be self defined.
