Recently I've decided to transfer all FEPoR Supports into RD, but it seems quite a chore to do a playthrough for each character support, so I need to know if PoR Supports are accumulative: Can I, for example, accumulate enough battles for a pair to be able to reach an A-level Support without actually watching C and B before? (Then in the last chapters I could develop C, B and then A for a support, then save Epilogue, transfer and start again with another support). Or do I need to have seen one support for start acummulating points for the next level? (In that case, I could develop two supports up to B, then do A, save Epilogue and restart going for the other A).
Maybe this has been adressed before, but I couldn't find anything. Thanks in advance ;)
