Not sure if there has been a new version since you posted, but I just tried and it actually seems to work well for me. I opened Air control, zoomed out to show the metro area, then scrolled to a new location, zoomed in to the location I want to fly in, then just click to drop a point, then click LAANC and that pointer becomes a box with handles I can adjust. The next screen lets me select the time / date. I'm running Air Control on Android.
