Which "Wideview Shinano"s are coupled?

[快速リゾートいっぺき]

I am planning to go on a vacation with my family (Though I don't know when will this pandemic ends) and it goes from Hamamatsu then Kyoto, Kanazawa, Toyama, Nagano, then back to Hamamatsu. I am planning to use the Shinano from Nagano to Shiojiri. Because it is toward Nagoya, It doesn't have the wideview seat, unless it is connected with another Shinano. Which Shinano are coupled?

As far as I know, all the Wideview Shinano (series 383) have the wedge-shaped end towards Nagano. The additional sets only have gangway fitted cabs and are at the Nagoya end, so unless you get lucky and a unit has been reversed for some reason, you will need to sit at the back of the train when leaving Nagano to get the Wideview carriage.
