Yes! If you add several colours/alternatives in your calendar settings on your phone you will be able to choose these in your Spond app going to your profile (top left corner) and press Calendar Settings and select different calendars for different groups under Group Calendar Settings.
This is very useful if you wish to differentiate between subgroups or several teams, as it will become easier to see which team is going to play
You can also add an alarm in the app. This alarm will not replace another alarm if you previously have added this manually to your calendar on events from Spond, but it will add the alarm as an extra alert. You can turn off the alarm you have manually added if you want to avoid getting two alarms.
