Transponder code reset after flight, option?

[tasss]

I fly with an AF-5500, and (I believe) a Dynon transponder. One problem is that it will squawk a previously set transponder code days after landing, which has led me to take off with a code I shouldn't have been using. Of course I try remember to set it when I land and in pre-flight, but it's easy to not notice, and it's a few presses to SET/XPDR/VFR when following the on-screen checklists.

While I understand wanting to retain the previous code in case of a power cycle, I imagine the majority of pilots (in USA, anyway) would want to switch back to some default (for me, 1200) following a power cycle after landing.

Is this something that's already an option? Is there some use case I'm not considering that would make sense to keep the previous squawk?

I came here to ask this question and found I already asked it!

So, maybe this is a feature request - is this something others have asked for as an option?
