Can I change auto-lock time on my iPhone based on which app I'm using ?

[iMore Question]

Generally I prefer the 1-minute option for security, but it gets annoying when I use my shopping-list application and it auto-locks if I cannot get to the next item in the grocery store fast enough. So I'd like 5 minutes if that app is in the foreground, otherwise 1 minute.

To answer the headline question...no.
