Suggested improvement for ChatGTP

I use chatGTP everyday for work. I have an idea on how to improve your service and/or my personal experience. I would love to see a more customized interaction. Currently, I have to type a personal prompts every time I need ChatGTP’s assistance, for example: “Send email to ABC, my name Larry, I work for XYZ…” I would like option to sign in & give CHATGTP my personal/business info for a preemptive prompts. Have it know my name is Larry, what company I work for and how I like to start my emails or messages. Even learn my speech lexicons to make suggestions that sound more like me or even on a person level, knowing I dont like brussel sprots when suggesting an shopping list or that I have dietary restrictions. I would pay for a ChatGTP personal assistant and a more organic interaction.
