LOW BATTERY RTL LANDING ADJUSTMENT

Hello, is there a way to adjust the Low Battery RTL Landing function? 20% is too much. I need the extra 5% to 15% battery level to get the shots I need. Yes I can plan all I want 'till Sunday but in the end things happen and a few seconds here may not be a problem but a few more seconds there of something that I may see and didn't anticipate I need to get it in the current lighting, but the darn H PLUS comes abruptly begins the flight home at 20% and this action is jarring and is not cinematic. For me it would be much better if the RTL switch activated at 15% or even 10%. Yes, I understand about battery level and not flying to 0%. I don't do that, but I always immediately charge my batteries (after they cool to room temperature) to STORAGE level. So the batteries are never below 5% on any of my other drones for more than an hour.

It just would be nice to be able to adjust the Low Battery RTL level.

Thanks.
