I just wanted to update this old thread for anyone reading.
I think this has been resolved with the Spelunkers subsystem introduced in the Side D expansion. It lets you hold the Move Up and Move Down controls to navigate the current branch of the cave. If you’re in the main branch, then holding Move Down will take you to the artifact at the end, and then holding Move Up will bring you back to the cave opening. If you’re in a child branch of the cave, then it works similarly, but holding Move Up will eventually get you back to the main branch. This feature is optional and can be toggled by upgrading or downgrading the Spelunkers.
It was this thread and subsequent discussion on Discord which led to this cool feature.
