### Describe the new feature

Hi,
I saw that it's possible to store and restore app settings from json file. But the file includes only general settings.
It would be great if it was possible to store and restore settings for chocolatey (servers URL for example)
Thanks

### Describe how this new feature could help users

With this new feature, UniGetUI deployment would be completely automatic.
For moment , the user needs to setup package servers URL manually on all PCs
