Why does Binance hide buy/sell history?

I mean, we need proper access. Right now, it is not displayed properly on the app nor on the website. I know we should keep track of our purchases to now our averages, but this is a basic service. Even on the buy/sell history there is no record of coins that I've purchased and that are still on my wallet. Why? Why do they hide this info from us? For example, I have BNB and there is not a single record saying when I bought it or how much it cost.

Binance makes it easy for people to buy/sell crypto, and i love that. But it also should make it easy for people to keep track of their money.
