Ability to set different background photo for each app #153

Hi Dev,
Currently we have the ability to set a single background photo which could be set for all the locked apps.
It would be great if we can set different background photos for each locked apps. This would make it really deceiving.

Example : If I wish to lock my playstore app, I would put a screenshot image of playstore and set it in the max lock settings. So if someone opens my playstore app, the screenshot would show up deceiving them as if it opens the playstore app.

Kindly include this enhancement in your next release.
