No, but if you want to know what teams are pending for an event, you could try posting the question in the thread for that event. Someone from the pending team(s) will probably reply. It worked for me.
To see if a team is pending/registered for a regional or the championship, you click on the team number, not the name and look for the regionals.
I’m pretty sure it may end up ludicrous because it means some teams are signed up for 4 regionals (2x the expected costs of going to championships and one regional) and many others are signed up for 3. Are the teams signed up for 3 and 4 regionals really financially ready to take on those regionals?
