How to disable DFF on Project Expenditure screen?

Hi!

How to configure DFF on the Expenditure screen when entering pre-approved batches transaction given this example? For example, i need to set-up 2 fields, "Reason" and "Date". However, there are specific reasons (2 - 3 reasons) that requires a date. If i will choose any of that reason, the "Date" field should be enabled and will allow to enter certain date. If not among those specific reason, the "Date" field should be disabled.
