Default gas price not saving

Hello, my Metamask has the option “Advanced Gas Control” but I cannot set a default value, it always goes to 5 GWEI in the Binance Smart Chain and while it’s good to pay default price, in time-sensitive operations when lots of people are trying to buy a limited edition item it always goes back to the default value, making the Metamask useless as the extra time spent for changing gas GWEI price is the time every item was bought by other people (and bots).

Is there a way to change and SAVE the minimal gas GWEI at a higher number? Is there any beta version of Metamask with that possibility? Do I need to make external tools to be able to do this? Thanks for the time.
