A workaround that might be helpful is via Process > Math > Macro.
An expression like "v=v*(v>10)" would set all pixels to zero if they are smaller or equal to 10, since in this case the bracket evaluates to false (equivalent to 0). You can play around with combinations of upper / lower thresholds via logical operators to achieve what you (might) want.
