Andras,
Thank you for confirming the limitations of the plug-ins. We will work on developing a solution that ties into the flow given that it is not acceptable for our clients to have to go back and forth and having to re-enter the same information multiple times. We have customers that could easily register a team for multiple events at once and this process will surely turn them away. Thank you again for your support, we will try to figure it out with custom code.
