It would be great if there was a feature to set default standard programming for different model phones so as soon as the phone is registered to the account then the button programming would get push...
The ability to create templates or copy/paste button configurations to different extensions would be a superb asset for not just efficiency, but also cuts down on potential for typos or misconfigurations. This is beneficial for all clients that have only a few buttons all the way up to those that have multiple sidecars.
To expand on this further, if it was possible to import a CSV that would associate/create a User, Device (by MAC), and button configuration that would be an added bonus.
