I have updated my signature line to reflect the Home Designer Pro 2020. I have watched the "railing walls" video listed below. In the video, under the "railing defaults", there is a tab for "rails", where he is able to to change the top, bottom, and middle rail profiles. Is this possible in Home Designer Pro 2020? I noticed in the video that the narrator appears to be using Chief Architect Premier X6.
