Is it possible to create a speedrun category for completing all tasks in slumber dojo in one run?

My suggestion would be that the tasks must be completed in sequence: first the first task, then the second, and so on, ending with the last one.

Time starts when selecting the first task end ends when the in-game timer stops after killing the endboss.

yeah that seems like it would be fun, like KFRRTA in smo or all KO arenas in smbw
