"Hey Jeff, Looking for a way to make a playlist file udm flag clean + turf debut horses only. Not seeing clean or turf debut as options in the udm wizard factors drop down. Help!"
There's an area of the playlist file part of the program known as preset filters. If you are operating in playlist file mode (which happens to be the program default) you would need to add the right filter code to a UDM to make it flag or avoid a given category of horse.
To get started, once you have the UDM brought up in the UDM Wizard, select FILTERS from the factors drop down and then click the Preset Filter Tool button. You would work the preset filter tool to arrive at the appropriate filter code(s) which can then be persisted to the UDM Definition. I've posted explicit instructions for working the preset filter tool here: http://www.jcapper.com/messageboard/TopicReader.asp?topic=940&forum=JCapper%20101
