reload only local-zones

[Josef via Unbound-users]

Hi list

Is there a possibility/command to reload only the local-zones, without 
flushing the whole cache? This would be great, because the cache did not 
have to be rebuilt every time there is a ressource record added or 
deleted.
When I do:
unbound-control flush manage.intra
it says ok, however the new data from the config file does not seem to 
be reloaded.

If there is no such command for reloading only the local-zones - would 
it be feasible to implement something like that?

Thanks
Josef
