How delete or edit Single Pages?

We can add a Single Page via Dashboard, but I don't see a way to remove or edit them once added. How can we do so?

I didn't see a straight solution too but reading the page linked below makes me think that things must be done manually. Needs to delete the page and upload a newer version.
What do u think?

Guys, Guys, Guys.. please.. don't ask you question in 5 different forums at the same time. Choose the one that is closest too it and then post 1 post there.
I am sure enough people just check on the topics that are active and if one is missed, just bump it.
