Unfortunately, not. Sideline Pro is treated as its own account type, and therefore cannot be used in conjunction with Team Number accounts at this time. Simply put, you have to choose one account or the other.
With that being said, our product development team is currently working on how we can offer the Pro features for Team Number accounts. There is no ETA on this yet, but we are working hard on getting this compatibility out to our Team Number accounts as soon as possible.
Thank you for your patience and feel free to contact us with any questions you may have.
