Dynamic Cell Access in Pigment

Hello Pigment Community,
Do we have dynamic cell access feature in Pigment?
For example:
 

I want users to just edit the Vintages and not the vintages that are already filled. 
(Context: This is a calculated field, but I have allowed data input override of the metric)
How can I just edit the Vintages and add values to the Vintages that are not filled and the ones that are filled or already calculated be non editable?

 Please kindly help.

Thanks!
