Question: Most people that have been practicing BJJ or most other grappling arts for a while know that it can be hard to maintain position while finishing a submission. This is why BJJ often has "backup" submissions or techniques in case the first one fails. For example, people that fail to finish a triangle choke (or lose the position ) often transition to an armbar and finish that way. 

But what I want to know is whether or not there are any existing submissions/positions in any martial art where you can actually finish two or more submissions at once without sacrificing dominance or giving up control. Something that I'm thinking of is some kind of armbar from a scissor choke, or just an armbar that is also Kimura or Americana(for those who don't know, those are both examples of powerful shoulder submissions). The reason that I'm asking is that if there is such a position, this could raise the finishing rate of myself and my classmates during rolling/sparring.

Answer: 
Yes. From triangle (*sankaku*) positions, there is the standard choke with the legs as well as the option to apply armbars. For example, from this side triangle position, if the choke fails, you can either cross body armbar (*juji gatame*) the near arm, or Kimura (*ude garami*) the far arm.

jigoku jime (hell strangle). Start with Hassami jime then jigoku jime. Ashi gatame - ude garami,
