I looked for 2 hours. I didn't find any Xposed modules, nor any apps that will do this on per-app basis. But you can change the response for your Android version. This is accomplished by changing the version in your build.prop file. This will be a PIA. It also involves some type of risk, so this will be on you if anything goes wrong. Read the last part of my answer more than once.
This involves root, build.prop file, backup build.prop, modified build.prop. Switching files around with a file browser. Rebooting. Using your app. Switching files around. Rebooting.
OR
Download one of the many build.prop editors
available on the Play Store. Find an open source one. You can edit the version inside the editor app. It will have options for backup of build.prop file as well. Rebooting still required.
ALWAYS MAKE A BACKUP/NANDROID WHEN MAKING CHANGES TO THE SYSTEM
