Won’t let me schedule driving over Glacier Park Glacier Route 1

I’m trying to model a drive from Fort MacLeod, BC charging to 100%, then to St. Mary, MT and over Glacier Route 1 to Lake MacDonald Lake and on to the Tesla Supercharger in Kalispell, MT. This is a plausible trip on one 100% charge, but ABRP won’t let me do this, it insists on driving the long way around down south. I’m also having trouble getting it to let me set the SoC at the beginning.
