How to choose which and when handlers will be executed?

Question

Let's say I have this code in Aiogram. I need that when the @dp.message(Text('Begin ')) handler is run, only the handlers that are inside this handler are checked. And when the user wrote End , then the handlers in @dp.message(Text('Begin ')) were no longer checked. And all that are outside this handler were checked

Minimal-reproducible-example:

import asyncio
import logging
from aiogram import Bot, Dispatcher, types
from aiogram.filters import Text
from aiogram.filters.command import Command
from aiogram.utils.keyboard import ReplyKeyboardBuilder

logging.basicConfig(level=logging.INFO)
bot = Bot(token="TOKEN")
dp = Dispatcher()




@dp.message(Command("start"))
async def cmd_start(message: types.Message):
    builder = ReplyKeyboardBuilder()
    builder.row(
        types.KeyboardButton(text="Begin"),
    )
    await message.answer('Hello, press to button',        reply_markup=builder.as_markup(resize_keyboard=True))


@dp.message(Text('Begin'))
async def new_client_services(message: types.Message):
    builder = ReplyKeyboardBuilder()
    builder.row(
        types.KeyboardButton(text="End"),
    )
    await message.answer("Please write down all your items lying on the table one by one",
                         reply_markup=builder.as_markup(resize_keyboard=True))

    @dp.message(Text('End'))
    async def end_save_services(message: types.Message):
        await message.reply("Excellent",
                            reply_markup=types.ReplyKeyboardRemove())

    @dp.message()
    async def with_puree(message: types.Message):
        #  add part mysql
        await message.answer(f"Items {message.text} add✅\n")


@dp.message()
async def end_save_services(message: types.Message):
    await message.reply("Please, push button")


async def main():
    await dp.start_polling(bot)


if __name__ == "__main__":
    asyncio.run(main())
