Yes. It's very easy to edit the existing activity and badge categories, or add new ones.
You can do this in two way:
- In 'Setup', just tap on the activity or badge icon on the right-hand side. You will see a list of all the current categories in your app. To add a new one, give it a name, choose an icon and tap 'Save'. To edit an existing one, just select it and then tap the edit icon in the corresponding box on the right.
- In 'Teach', scroll through the list of activities or badges and tap the 'blue +' icon. Then just choose an icon, give the activity or badge a name and tap 'Save'. You will then be able to post or award it immediately, and it will be saved to your appropriate bank of categories.
