Can’t do that here either.
The way it used to work is when you renewed your plate PennDOT would send you a sticker with the year, which you placed up in the corner. A few years ago they decided it was a waste of money to print and mail these by the millions each year.
When your car passes state inspection the mechanic puts a separate sticker in your windshield.
In Texas we get the registration sticker, but not the inspection sticker.
