[Gretl-users] make a prediction with other confidence interval

hi people, Before my question, a little explain: I have a time series (gasoline sales) from january:2000 to december:2007 and i´m adjusting a sarima model to make predictions. Well, i´m running a sarima model with parameters (1,1,0)x(1,1,0). After running the sarima model, by default, the prediction is made with 95% interval confidence (represented by the green bars). My question is: In gretl, can i make a prediction with another interval confidence (90% for example)? I post the pic at http://br.geocities.com/asilva_rocha/question_gretl.png to make the question more clear.
