When coming to interfacing many seven segments it is advised to use decade counters in order to conserve the number of pins you dedicate to the seven segment. But iam not sure i understand your question fully but upto my understanding using this**broken link removed** can solve your problem and also allow you to handle the segments more easily. Let me know if it helps
