How can I retrieve the last 20 web pages that I had open in Safari?

Hello to the people who program this stuff at Apple.

I was researching a car problem and had very many pages open. For a reason I had to shut down the computer and a day or so later attempted to reopen Safari. None of the pages came up and I found this (pict 1)

This is available but only in some specific way and I obviously missed it. So from what I can see I can look through my history (which is a HUGE amount of links) for the days it took me to find the pages I needed. Or I can just start the search all over again, which I have.

Yes I should have done this or that. Please don't waste all of our time with those kind of comments.

What you could do is change the "Reopen All Windows from Last Session" to "Reopen All Windows from Date ab,xy,vbnk" Pardon my example, I hope you can figure out what I mean.

Thanks for reading it and or passing it on.
