How to turn boiler on at any pressure water

How to start combi Boiler when turning on sink tap at any pressure please? The boiler clicks off less the water running is high. Which means when I wash up every day the hot water goes cold or not hot enough between washing up a plate or two, unless I keep the tap running throughout. It gets very hot if I run the water, so this isn't the temperature of the water that's the problem, it's that combi boilers don't store hot water and it goes cold when turning it on and off. But when I keep the tap running I waste a ton of water (wasting water and energy bills) because the boiler clicks off unless the pressure is coming out fast. I want the boiler to go on when I run the sink tap at minimal (ideal any) pressure. The same happens in the bath. When I want to top up the bath with hot water, I turn the hot water tap on but I have to run it really strongly to start up the boiler. By which point my bath water is freezing. I want to turn the tap pressure down and wait for the boiler to heat up the hot water, then crank the tap to full pressure. Thank you for advice on whether this can be changed and how. Its very annoying and badly designed if not! Edit: thanks for replies. Engineer looked and said nothing wrong with boiler. He said you guys may of been getting confused between me talking about pressure, and thinking it's pressure in boiler not the amount of water coming out of tap fast as water "pressure". He said it is to do with flu flow rate - that enough water has to be running for boiler to start and I can't change that. When I rinse plates or run a bath I HAVE to have water coming out fast. I have no choice. Can't have showers as disabled and no screen either. I said it's worse in winter as water already cold to heat up so running fast water rather than just gently running it. And also he said my cold water now measures colder than the average. He said about 10 degrees when average cold water is 11 degrees. But can't change that I have to run the water pressure high in order for boiler not to click off. 😟
