My company has a specific format for weekly updates, and, frankly, it's a pain to put together.
So what I do is I take notes in a doc throughout the week (Obsidian periodic weekly notes) and just send all of it to a custom GPT that creates the update for me. I usually then spend ~10 minutes cleaning it up.
I'm generally allergic to having an LLM write for me, but seeing as it _must_ be in the requested template and ChatGPT saves me a couple of hours, I let this case slide.
