Thank you for your valuable feedback. We are pleased to inform that we have taken this concern into consideration and will be deploying this feature in December.
This privilege is already supported in Acrobat and we will now be supporting the same in Reader as well.
Path in Acrobat : Hamburger > Preferences > Documents > Restore last view settings on reopening the documents.
