1041 - Make Capital gains part of Distributable Net Income

The trustee of our trust has a lot of discretion, although it is not spelled out, specifics are left unsaid in the document. We want to make a distribution to beneficiary and besides the usual DNI, we want to also include part of the capital gains as DNI, so it is taxed at the beneficiary level. I wonder how we would do this in the TT Business software. Is there a separate schedule or form where we could specify that?

thanks
