Update settings/reprovision automatically without factory reset

[FrankDRNS]

Is it in some way possible to update autoprovisioned settings without having to factory reset? Like on some handsets such as the W53H you can go into settings and find an option to reprovision manually. However, you do need the password/pin code in order to get there, which is information we don't usually share with our customers. Plus the fact that the customer needs to follow some steps which usually they don't really care for.

Basically what we're looking for, is a setting such as autoprovision.update_interval = 3600. Then every hour the phone would check the autoprovision URL and see if the settings changed since last time.

I understand that some settings can not be updated while the phone is turned on (such as VLANs), in which case it should either A) still be done with a factory reset B) be handled through a second flag such as autoprovision.update_restart_allowed.
