EHS. How to reload the config XML file?

Hi. I have a customer who wants to modify the Wallpaper or the Title shown by EHS v1.6 on the fly by his business application. I was searching for an intent to do that but it seems to be not possible except rebooting the device.

Is it possible to have an intent to update the title with a custom string (maybe the IP address) or the wallpaper? Or even to reload the whole XML without restarting?
