Nope, not really.
Here is how to determine which screw is which.
Front derailleur. Shift to the lowest chainring. The screw which while being tightened (clockwise) moves the body outwards is the low limit screw - L. The other screw is the high limit screw - H. If you shift to the big chainring and start tightening the H screw the body should star moving inwards.
Same goes for the rear mech. For L screw, switch to the bigggest cog. For H screw, you need to switch to the smallest cog.
