Other than Kevin Mcleod's Depth Cruiser which maintains the sub at a specific depth you set with the stick has anyone made an electronic device that will take a sub automatically to a preset depth like periscope depth (0.25m), operational depth (1m) and max depth (3m) using a 3 position switch on the transmitter?

If you use a transmitter with programmable throws and can set the 3-pos switch for different pulse outputs, you can do that with standard depth controllers down to 1 or 1.5m. Below that will require something bespoke, however anyone with any experience at operating model subs will tell you even in clear water below a a metre or two is pretty uninspiring as it's difficult to see what the boat is doing.
Get a boat going and you can experience this for yourself. -
Yeah I realized 3 meter is too much. A better option would be surface, periscope depth then 1 mt operating depth.

I think your question highlights the difference between a hybrid dynamic/static diving system and a metered ballast system. In the hybrid, the sub is ideally trimmed to a portion of the sail being above the surface. Subs by Engel and Engelhardt use a Piston Tank as a ballast system and can trim to periscope depth. Thereafter, pitch control alone maintains that depth as demonstrated in Bob Martin’s latest 212 video. With the hybrid system, you need forward momentum and dive planes to maintain depth. The forward dive planes are used to correct the positive buoyancy since the stern planes can only correct for pitch. The forward dive planes need depth feedback to maintain autonomous depth control.
The hybrid system is simple and reliable but it complicates depth control. A metered ballast system is more complex but enables true static diving by attaining neutral buoyancy. The hybrid system is also inherently safer in failure mode since there is a chance it will eventually surface barring water intrusion.

Nearly the entirety of this discussion -- though academically informative -- is wasted on those who actually play this game successfully in an open body of water.
Too much seeking-answers-to-non-existent-problems going on here.
Andy is point on with his comment, and did it without being blunt.
I'll be blunt: You don't need a dedicated 'depth keeper'! A dialed in angle-keeper and a PROPERLY TRIMMED boat is all you need. KISS!!!!!
