Digitizing Yarn/Whip fill effect

Can anyone help me with any info regarding digitizing this stitch effect. I've seen it sewn mostly with cotton thread and it looks like a fill stitch that runs back and forth before moving on, similar to a bean stitch I suppose. I'm using ApS Ethos right now and it doesn't have any stock effect that would give me this result. Is it a stitch effect available in another type of software, or maybe the fill effect needs to be created? Thanks.

Hi Karen,

I understand about editing the stitch length for my different fill stitches, but I'm at a loss as to how create a fill effect that will stitch back and forth several times(at the determined stitch interval) before moving on. When you digitize a design that gives the same result as my pic is it just a stock fill in your software that you use or did you have to create a new fill effect or edit an existing stock one? Thanks.
