Hello Syed, welcome to the forum.
In the latest version of PVElite (version 2004), we have added a new 'button' to the nozzle dialogue screen. Look for a button labelled 'Layout'. If you click on this button, you should be able to install a hillside nozzle easily. In the Layout screen (once it opens), there is a help button at the bottom. If you click on that help button, the full instructions for installing hillside and radial nozzles is explained in the pop-up help screen.
You might find it convenient to do a little experimentation to get the hang of this new feature, but it (we feel) should make life a little easier than the older method of installing hillside nozzles. The new method is much more versatile.
Thank you for your question, and interest.
