Not just that, the initial scan is the real pain nowadays. I think Xeno Scanners should be folded into the standard Sensor Suite by now, but alternatively, the existing module could receive longer range, fast scan, or a combination thereof.
You can bind next and previous sub-target rather than navigating the menu, the issue for me is having to get a successful xeno-scan off before having the ability to sub-target.
An integrated Xeno scanner (short range) and a longer range fitted scanner are both viable candidates for CGs that improve the tech to fight the thargoids
