-walletnotify on 6 confirmations instead of 1? Pretty straight forward. Right now im using -walletnotify to run some node.js code when i get an incoming transaction and when theres 1 confirmation. However, after reading around, i found out that 1 confirmation is not secure, which now makes me want to execute this confirmation code when theres at least 6 confirmations. 

TL;DR, Is there a parameter or an equivalent for -walletnotify to run on N confirmations?
This is not possible with the current version of Bitcoin-Core (0.13.1).
