Team Section alignment

Hi all I use the Team Feature for our Band members. http://www.defactoo.com/ipdogz/ We are 5 members and i have set the the Layout to 3 Columns. It would be very cool to have the addidtional to members in the Second row centered. Now the alignment ist left. Is tehre a possibility to change that, or can i set a 5 column layout? Thankes
