Manually updating 52-week range

I did not want to move to the subscription model, so I am now manually importing security prices into Quicken 2016. Is there a way to manually import the “52-Week Range”? I currently import closing price, high, low and volume, so Quicken has enough data to calculate the 52-week range. However, it does not. The 52-Week Range is frozen at what it was on April 30, the last day I updated prices through Quicken. Is there a way to fix this, short of paying for a Quicken subscription that I otherwise do not need or want?
