Linking to a portfolio project

Hello. I find it wonderful that I can link to pages within my website instead of just having to use URLs. However, this feature doesnt seem to extend to pages that are projects within a portfolio. I have many portfolio "project" pages, and I'd like to be able to link to them just like I do any other page on my website, by linking to the page rather than the URL for the page. Is this possible? I dont believe it is but I'd like to double check either way. 

If not, I hope this feature gets added! Some of my links become innactive over time, and when I get a new URL for my website I'll have to go through and edit every single hyperlink thats using URLs instead of pages to redirect the user to said pages. It will be quite time consuming. 

I have the same issue, would like to link to specific portfolio pages but only have the option to link to the main portfolio.
