Jumping- To loop or not to loop?

Im trying to get my animation to jump but im using a specific (magic user version of Idle_Walk_Run
so i cant use the default Jump;Start,loop,end animations

So… no where on Mixamo was there a Jump Start loop end set of animations just several versions of a
single jump animation.

So my question is…
Do i need a Jump loop?
If so… how can i convert one of the jump animations to a start,loop,end set.
i tried using the montage for it but i couldnt quite figure it out and i couldnt find any
tutorials on converting the jump animations to montages or converting them into seperate animations.
nor could i find any tutorials on setting up locomotion for anything but a jump LOOP… and founf nothing on just a jump.

What should i do.
