Custom Reports- missing unique pageviews as a variable

Hello!

We have noticed when you create a Custom Report with the dimension Page URL you can not combine it with the variable unique pageviews.

We would like to be able to combine Page URL and unique page views. It seems the dimension Page URL and variable Page views can be combined. But can it be possible to add uniquie page views as well as a variable to Custom Reports?


1= Dimension Page URL
2= Variable Page views
3= Variable Unique Page views does not appear/can not be chosen

It would be helpful to us and probably many more. Thanks for your time!

Best regards
