    It's not a supported feature within the framework, but there is a feature request for it. You should be able to find a user extension which meets your needs, such as this one:

    Hi,

    Can each of the three-states have its own visual representation ?

    Are the only display values the check symbol , and the absence of the check symbol.

    What our users would like is that the checkbox should only appear as blank, if it has not been updated
    by the user (i.e. null).

    For example - could a check symbol represent a 'Yes', an 'x' symbol a 'No', and the blank represent that is has not been set
    or that user is deliberately desisting from assigning a value (to represent an 'undecided' value) ?
