Any Way To Disable "Auto-Best" ship designs

[Blue001]

Any time I get a new ship Tech, my ship designer is filled with new "Auto-Best" designs that I have to delete. Isn't the Auto-Upgrade checkbox supposed to just upgrade my current designs to better version without making whole new designs?

There's the auto-upgrade for each design on the right side, and there's the auto-design on the left.
It's been like this forever.

Oh, weird, Ive never noticed that little check in the left corner, I've played mutiple long games and never had to uncheck that. Maybe it was defaulted off before? Thanks.

I have a similar question, except in my situation I'm looking for a "crippling" solution to the auto-upgrade feature.

I've build myself a galaxy fully composed of species I created with fleets including ship names, compositions and designs I've planned for the specific empires (19 of them to be exact). It took quite a while and I'm nearly done with all the details, except the stubborn AI keeps upgrading the designs as soon as I move back to my empire--even though I make sure the box in ship designer is unchecked. It's extremely frustrating, that my enemies won't use the weaponry I've set them all up with. And an aesthetical disaster in most cases...

Is there a file I can modify to prevent the AI from using this feature? Something I can mess up so the auto-upgrading doesn't work at all?

I don't know for sure that what you are attempting is even possible, but if it is I suspect that the solution would involve making a mod. Maybe there's a way to mod auto-best out of the game, for example.
