Can I feed two mppts in series?

I currently have one 100/20 smart solar, I am planning to expand my system, but I don’t want the expense of running another pair of wires from a second arrow to the second mppt. Can I for example assemble a 200v array and connect the two mppts in series so they both see 100v? My 200v number is just an example, I wouldn’t go that close to the full rating,

No, it would not work, when one is reducing it's resistance seeking the MPP, it would increase the voltage on the other and maybe toast it.
