In some cases, you might want to create two campaigns, a pre-launch and the main launch for example.
You may want to transfer points contestants collected during pre-launch and have it transferred to the main launch.
This is not possible since each campaign is separate from one another, however, there is a simple workaround.
You can create the pre-launch campaign and when you're ready to do the main launch, just change the design/text/bonus actions of the pre-launch directly to reflect the main launch.
In other words, it is possible to modify your campaign while it's running. This will allow contestants to continue participating while retaining their points.
