Hi JammedStab,
I think the 744 does have a somewhat similar feature in that if you push TOGA on takeoff between 50' and 400', LNAV will change back to TOGA roll mode. If you push TOGA above 400', both TOGA roll and TOGA pitch mode appear on the FMA.
Also, if you push TOGA after liftoff (with takeoff reference thrust displayed), and the A/T is still in HOLD (prior to 400'), it will remove any derates and activate the A/T in THR REF mode.
