It's not possible. I hate the new way myself. The new way requires tapping on a favorite and then selecting call or message.
Did you know that you can assign the numbers on the phones keypad, one of your contacts?
On the phone apps keypad, pressing and holding the number 1 will dial voicemail. You can assign a contact to any of the numbers on the keypad by long pressing a number and then in the popup, tap OK to assign a contact to that number. You would then just long press that number to call that contact. I have number 2 assigned to call my job. It's not the same thing but it might make things easier for you.
You can also quickly edit the speed dial numbers by hitting the three dots in the top right corner of the search window.
