Hi, yes there is.
I think you have done a print rotation "in the queue" rather than an image rotation.
Right click on the thumbs or images on the page preview and select Predefined Filter. A list of Filters will appear so then choose the appropriate rotation filter and ok.
When you convert, make sure "Apply associative filters if they exist" is selected with a dot. That should do it.
Are your portrait raw thumbs not showing as portrait? If so, check you camera settings so that rotation is automatically detected.

The way I do it is to put the RAW images into the queue. Go into the editor. Apply the rotation that you want, apply to all in queue and SAVE AS TIFF.
The save as... is one at a time. If you have a load to rotate, then use Terry's method. Works fine
