Charging Multiple Voltage Batteries?

For you guys that are running multiple different voltage batteries (16v for electronics, 12v for motor, 24v or 36v for trolling motor, etc), are you using multiple chargers or each battery? I was considering at some point changing my battery setup and was wondering if anyone made a single multi-volt marine charger, but I can't seem to find one. Not looking to purchase anything soon, mostly just curious.

I have 3 12v batteries, 2 for the 24v Ultrex and one for cranking and electonics and use a Noco 3 bank onboard charger. Each bank charges one battery. Some guys have a single 24v or 36v Lithium battery for their trolling motor and use two chargers. One for their 24 or 36v Lithium and one for their 12v cranking battery.

If you have multiple 12v batteries wired for a 24v or 36v, you still charge each battery with 12v.

Yeah, I'm using 12v batteries for everything, but I'm talking about charging a mix of multiple different batteries that are different voltages from the factory, not 12vs wired in series.

I don't think anyone sells such a critter yet, but with all the 24v and 36v Litiums that are now available I wouldn't be surprised to see someone like Noco bringing one to market.
