Here is how I did it. Video / GIF was too big so I have saved screen shots to the pdf file. Basically dimension your sketch to radius and make it less than 180 degree. Go back to drawing and do arc dimension, it will come out just as you want it and then go back to model sketch and make it 180 degree.....surprise your drawing will keep the arc dimension the way you want it.
its not a standard, but a solidworks glitch when sometimes it decided to place arc length dimensions this way. Happens to me pretty often. The way around it for me is to draw an arc on the drawing over the edge I want to dimension and dimension that for the arc length, this will usually get the dimension you want.
These settings got me this result. The only difference being the position of the leader lines are vertical where your inventor shows horizontal ...
