Actually you can but it requires you to convert your Peercoin address to an NSR address and send all your NSR to this single address.
But then all your NuShares and Peercoins will be locked by the same private key. That may not be what you want.
To convert your address it may be as simple as importing your Peercoin private key into your NSR wallet, because in previous releases we used the same private key format as Peercoin so we continue to support it.
so you’re saying that if I go into NUSHARES wallet and do an importprivkey PEERCOIN PRIV KEY HERE my dividends will go to the corresponding address? (I’m okay with my nushares and ppc being linked to the same private key, thats my aim, actually)
If after the import you send all your NSR to the imported NSR address then yes.
If by that you mean stop generating a new address each time the client has change to send then the answer is yes. It’s done by enabling avatar mode, which is enabled by default on the NSR wallet. Change is sent to the sending address (or the first sending address if there are more than one).
