no, but there is one that can fill your POke Dex completely.
FOR THE SINNOH DEX-just battle everybody ever. Cynthia has a few than you can only see with her(unless you eveolve them yourself). FOR NAT. DEX- Pal park, friends, poke Swarms and poke radar.
You get the national dex when you beat Cynthia. And get the poke dex at Rowan's lab.
Get the national poke dex and talk to profeser rowanTo do that you have to see every Pokemon in the small poke dex you will get the Poke rader! :]

The answer is "No". You only gotta know it's number in the National Dex, that's all.
