Implement/document a way how to pass information between handlers

I came across a situation where I scrape half of the item's data in the listing page handler and the other half in a handler taking care of the detail page. I think must be quite common case. I struggle to see how I pass the information down from one handler to another. See concrete example below:

import re
import asyncio
from enum import StrEnum, auto

import click
from crawlee.beautifulsoup_crawler import (
    BeautifulSoupCrawler,
    BeautifulSoupCrawlingContext,
)
from crawlee.router import Router


LENGTH_RE = re.compile(r"(\d+)\s+min")


class Label(StrEnum):
    DETAIL = auto()


router = Router[BeautifulSoupCrawlingContext]()


@click.command()
def edison():
    asyncio.run(scrape())


async def scrape():
    crawler = BeautifulSoupCrawler(request_handler=router)
    await crawler.run(["https://edisonfilmhub.cz/program"])
    await crawler.export_data("edison.json", dataset_name="edison")


@router.default_handler
async def detault_handler(context: BeautifulSoupCrawlingContext):
    await context.enqueue_links(selector=".program_table .name a", label=Label.DETAIL)


@router.handler(Label.DETAIL)
async def detail_handler(context: BeautifulSoupCrawlingContext):
    context.log.info(f"Scraping {context.request.url}")

    description = context.soup.select_one(".filmy_page .desc3").text
    length_min = LENGTH_RE.search(description).group(1)
    # TODO get starts_at, then calculate ends_at

    await context.push_data(
        {
            "url": context.request.url,
            "title": context.soup.select_one(".filmy_page h1").text.strip(),
            "csfd_url": context.soup.select_one(".filmy_page .hrefs a")["href"],
        },
        dataset_name="edison",
    )

I need to scrape starts_at at the default_handler, then add more details to the item on the detail page, and calculate the ends_at time according to the length of the film. Even if I changed enqueue_links to something more delicate, how do I pass data from one request to another?
