[library addict]

Could a setting be added to have the Read and Date Read columns only sync from Calibre to CC and not vice versa?

The reason I ask is that I have the "Update Date Read when read" box unchecked in CC. I like to have the date read as the date I finish I book which is not always the same as when I start it. I was adding some new books to CC from my main Calibre library and the rating, date read, and read info for the last two books I'd updated as read in Calibre synced over fine as well. Then I changed to one of my other libraries to add another few books to my Nexus. But when I disconnected the device and then switched back to my main library in Calibre I noticed the date read and read (yes) info for the two books had disappeared from Calibre (and checking from the Nexus as well).

I add books from two of my libraries to my other readers routinely without disconnecting/reconnecting my devices. But that's through USB. Am I not supposed to switch libraries when wirelessly connected to CC? If that's the case I can be sure not to, but I don't want the date read info wiped out by accident so would prefer an option to have the sync to go only one way if that's not a big issue.
