You actually have a interesting idea here.    I wouldn't be interested in such a feature on this console.  But to link a tablet  to a online multi-player PC game where a player assumes a commander role and tactics are extremely important  would be a great feature.    Even more so if the commander doesn't even require a PC to begin with and can command games across the globe.     Instead of  simply saying "Squad Alpha go to this point"  The commander could even draw out a suggested path from the troops to follow if the commander knows of  dangers lurking or to better setup ambushes.  
Consider your idea stolen as I go tell a buddy of mine about this.
