You can merge two TouchCasts by going to "My TouchCasts" and follow the three steps to easily merge two TouchCasts:
- Select the edit pencil in the lower left corner
- Then choose the two TouchCasts that you'd like to bring together
- Finally, tap "merge" on the top right corner.
You can then arrange them in any order. This will create a new TouchCast all together, so you are not losing your individual TouchCasts. Note that your TouchCasts cannot be over 5 minutes combined.
