I’ve been doing merged namecoin/bitcoin mining with Slush’s pool. I can see a payout of numerous namecoin, but it doesn’t add up in bitparking. Bitparking appears to only show the last namecoin payout and not all payouts combined.

I have one namecoin address in Slush's pool setting. But when logged into Bitparking, I only see the last namecoin payout. Where's the rest?

Can I combine namecoin payouts to one namecoin address?  If not, how do I add additional namecoin payouts to bitparking?

Thanks in advance!!
