Space bar to select text

Hi community! I have come across a situation where I want to select a text in my iPhone by pressing the spacebar on my keyboard and then holding with another finger on any other part of the keyboard to move the spacebar finger freely and start selecting text. I hope I was clear about which function I am referring to. The issue however is that I often find myself selecting more than I wanted (going over to the next characters by one or two) and I can’t go back. This might be a very small detail, but I really think it can be beneficial to change the function so that your selecting point is a pivot and the sliding finger moves the selection to the right and left from the same end of the selection area. Right now, when moving the finger to the right or left, the text selection gets larger from each side of the selection, but it can’t be shortened when a mistake like going over happens, at least in the same maneuver. I believe it’s very easy to select the desired pivot where the selection will start, because the user can first hold and slide the spacebar to locate the vertical bar in the text and then hold with second finger to start selecting. That means that being able to move both ends of the selection area is not necessarily providing a uniquely useful advantage. Thanks for reading, I hope someone understands what I am saying and the apple community is able to fix this inconvenience.
