Using Tomorrow's Power for Delivery?

Just a random thought - why doesn't Tomorrow use her ability to deliver cargo? The dive through tar method won't work since it'd be similar to delivering with the Megallen, but the >!Sam-perpetually-on-fire cutscene shows Tomorrow dragging Higgs on the ground while kind of gliding on tar!<, which means she can carry stuff while not going into the tar completely.

!The post credit scene shows Tomorrow/Lou taking on the delivery job, but her power would make terrain traversal a piece of cake wouldn't it? !<It's like she got a built-in coffin board. I feel like the crew could've taken advantage of this ever since she got full control over her power
