Ability to attach motion to a playcall

When you call a play on offense, you should have the ability to attach a motion to it. So basically you call a play with either a motion or not a motion. This doesn't affect the play art and doesn't require a new play. Basically when you call the play, one of the receivers/Tight Ends etc. is lined up somewhere else and then motions into the correct position to run the play. The developers could just program into each formation how the motion would work. So basically for a specific 3x1 formation, you line up initially into a 2x2 formation and motion into the play you just called. 

The benefits of this system would basically make pre snap motion feasible without having to hot route to a make a play feasible. Rather than having a handful of motion plays in the playbook, now every play can be a motion play if the user decides to do it. You can then disguise plays better and read coverage better as well.  This will add another layer of strategy to offense.
