HI Mark, you are correct that the publish source for slope settings is no longer available in 8.x in the Set up tab. However the Results work sheet can be copied to the data folder if required, althoigh generally I recommend to keep this useage to a minimum since it disconnects this sheet from the workflow and it won't be automatically updated if data changes.
it would be better if you have to make some edits to it to use a Data Wizard, and if you aren't changing it, then just map the results sheet directly to where needed.
