Hi Zhenbo.
Is it possible to make custom fields available in specific portfolios?
I have two different portfolios and I would like it if I could make custom fields used in one portfolio available only in the dashboard for this specific portfolio.
If I add the fields in the "Dashboard Fields per Dashboard Type", the fields become available in both portfolios.
I then tried to create a new entry in the "Dashboard Fileds per Context", but I didn't succeed in making the fields available in specific portfolios.
So my question is if this i possible and if so how? 
Best,
Morten
