All of the major appliance manufacturers will offer a line of electric ranges with a variety of options, from a no-frills range to one that's loaded with every feature you can ask for. I expect that all you need to do is buy a different timer (from a more expensive range) for your existing range; one that has the feature you're looking for.
You will have to compare the wiring diagrams of both your existing range with your existing timer and the more expensive range with the full featured timer. I expect that if you go to your local factory authorized service depot for your brand of range, they could both supply you with the correct timer and the wiring diagrams and give you the help you need if you want to install it yourself. You will certainly pay more for the timer buying it from the factory authorized service depot than buying it from an appliance parts store, but at the service depot you get free tech support from the appliance service technicians to help you get it installed properly. These appliance repair techs have access to the people from the factory that train technicians to repair their ranges, and those people in turn are in continuous contact with the engineers at the factory that designed the range. So, you at least have the knowledge and expertise available to you on how to swap out the timers if you buy the timer at the factory authorized service depot.
If it were me, I would start by finding out who the factory authorized service depot for your brand of range is, and then talk to the guys there about what you want to do. They'll tell you if it's feasible or not, and I expect it will be.
