Can I reset all progress on challenges in the cat photo app project

Does anyone know of a way to reset progress back to 0 for the cat photo app curriculum? (Basically undo all correct submissions so that it looks like no steps have been completed)

you can reset your whole account, but not a specific section/certification


Thanks Ilenia. Can I do this myself or I have to ask someone? (Not asking for this account btw)

it’s in the settings
