Can Basecamp do proper hiking route estimation INCLUDING height gain/loss impact?

When I create a route for hiking, Basecamp does not seem to take into account height gain / loss, even though it has this in the route summary.

That's obviously completely useless as unlike driving it has a big impact on timing.

I confirmed this is the case by simply inverting a hiking route to the top of a hill - up and down give the same time.

Am I missing something here?
