Storing owncloud Desktop client credentials by third party software

By using the owncloud client wizard, the credentials get stored in a config file on the local machine.
Is there a way where i can make Owncloud skip the configuration wizard by setting these config values myself?
The password is in some way encrypted which doesn't allow me to set it myself. I looked into the Github source but my knowlegde of c++ is nihil. Does anyone know a way of doing this?
