No, I have not. I wouldn't use it for my goals, personally. It would supply far too little Nitrogen over the season at random times when it may not be helpful, like summer.
Pre-emergent goes down weeks before your turf likely needs a heavy dose of Nitrogen anyways, and I like to have more control over when the Nitrogen is released into the soil.
Spreading out 1 lb of Nitrogen per K over 6 months is underfeeding PR, fescue, or KBG. It needs much more than that unless you want a better-than-doing-nothing lawn.
