Daily average before a trip

Hi team!
I would love for future trips to calculate the daily average based on the costs I’ve added to it, right now it tells me to wait until the start date. Seeing the daily average ahead of time helps me limit my spending and keep me on track! It would also be cool if when adding a budget to a trip, to be able to add a daily budget instead of the overall cost (and the app tells me how much it will cost overall).
