E18 Is there a way to synchronize individual grid variables in a group?

    Not at the moment. This was a design decision partly to be able to
    support "compact" groups of variables in the future (that is, groups
    where the group members at any grid point are stored contiguously in
    memory ... compared to the "normal" way we have now where each group
    member is stored as a different array). With compact groups synchronizing
    single members would be more computationally expensive. Currently
    the infrastructure is mainly built around the concept of groups of
    variables, and changing this would involve changes to the driver
    interface.

E19 Is there a way to synchronize just one time level of a grid variable?

    Right now only one time level is sychronized, that is the "current" level.
    Other time levels cannot be synchronized and are assumed to be fixed
    or read only.
