Custom Column: Default value when column is null

I have a field that is sometimes empty or null. Without writing a native question, I’d like to apply a default value to this field using the Custom Column feature. Is this possible?

Hi @Mr.ScreenName
Depending on which database you’re querying and which database column type it is, then there are possible workaround.
