Disabling Readycloud on a share by share basis

I have setup ReadyCloud for my NAS and everything works fine. I have a couple of shares that I would like NOT to be accessible remotely at all, not even by the admin user. Is it possible? From the readycloud page it does not seems possible because I can set permissions only for additional users and from the NAS admin page I cannot untick the readycloud admin email.

I mean, I just want these two shares to be accessible only from the local network, but not remotely.

I was suggested to post it here because there is not feature like this. Any interest?

I believe it's reasonable to want data on the nas to be accessible from the network, but absolutely not to have it online, not even for the admin.
