You can! If you go to your keybinds, there is a confirm keybind in there somewhere. I can't remember where exactly, but if you set your confirm keybind to a button (mine is w), it will confirm the choice selected in your mining list. There is also an option for targeting in there that let's you target objects (such as mining nodes) so that you can select the node with that button, then confirm your selection, then confirm your memorized cursor and mine to your hearts content!
