Change the tab on which the member page opens

We receive a lot of cash payments. After I type the name of the member and open the members page, it always opens on the "Reservations" tab. I would like to see that it opens on the last used tab (in my case that would be billing). Or that it would be possible to determine the tab on which it opens in Settings. This way I don't have to click "Billing" each time I open the members page to process 20+ payments.
