MK167 Tealight Candle 3Vdc power supply & remote switch?

I would like to use a 3v DC power supply with the kit. I want to be able to switch the power supply on with a remote switch and have the candle activate in the flickering flame mode only. I want to turn off the candle using the same remote power supply switch. The problem is that the switch supplied with the kit is a momentary contact switch and the power supply switch would be either on or off supplying power to the circuit.
I want to disable all of the other modes (other than the flicker mode) for the candle and will likely have to bypass the small switch that comes with the kit, again this is a momentary contact switch so I need to know if I can work around this maybe by not connecting all of the contacts on the IC that is supplied with the kit. I would also like to disable the 5 hour off timer - I don’t know if this will work when using the power supply switch as the only source for switching device on and off.

Please Help
