question on data series security

Hi,

From my experience, we can not define read&write for data series for Demantra user. if the series can be editable, once I assign to user, they can edit, no option to assign a editable series to a user with read only permission. if this is true, I am not sure if there is workaround for the following scenarios

For Example,

I have 2 users, each user cover a country, user 1001 cover fcst in country A, user 1002 cover fcst in country B. The trick is, user 1001 need to see country B's CONSENSUS FCST. we have one editable data series CONSENSUS FCST, both user use the data series to enter fcst, is it possible that user 1001 can see forecast made by user 1002, read only, thanks a lot
