Could we open supply challenge speedrun category? It's fairly interesting and entertaining scenario. There are many speedruns at youtube

Supply Challenge used to be a category. There were some submissions 4 years ago. We removed it like last year due to inactivity for over 2 years. It was superseded by the "Getting on track like a pro" category which became way more popular and seems to attract the same runners. There are currently no plans to add it again until it will be more popular again.
