Nope, this isn't/wasn't a Litecoin-feature.
Back in my Litecoin-days I wrote an external shell-script which first made a backup of wallet.dat and then started the wallet itself.
This isn't exactly end-user-friendly, so I decided Dash needs something integrated into the wallet itself.
Is it possible for you guys (fabulous DASH devs) to create some automation in the creation/management/updating of masternodes? Make it so that you don't have to be a Linux savant to be a masternode owner? (I know that's an exaggeration but....)
It would be awesome if the majority of what we have to do as masternode owners could be done through the wallet.
