Timer for economy 7 Water heater

Hello, I have a problem with an E7 water heater which means there is no longer the option to have both peak and off peak feeds connected to the element - the tank was replaced with one with only one element but the previous one had two.

So at the moment, I have chosen to connect the peak feed cable to heat water in the day for washing up or a bath (manual switch with a cable to the tank element) but would like the option to heat the water as well on the off peak over night. All the timers I have found have only one inlet point and two outlets to the assumed peak and off peak elements. But I need two inlet points and one outlet to a single element. The timer would then need to choose which inlet source to access depending on the time set e.g. timer set for 5-6am would draw power from the off peak inlet.

Do such timers exist? Thanks in advance for advice.
