Find a trend regressor for arima model

Hi,

I'm doing x12-arima seasonal adjustment for the series that is stationary at level with intercept and trend components. I know how to add constant regressor "const" in the model, but I still can't find a syntax for a trend regressor. Please help.

How come adding the option "iatip=1" gave a different outlier since it enabled auto detection?

Thank you
