For any specific predicate, can we have custom group id instead dgraph decides by itself?  
And can we manually control the groups which should go to which shard?

You can use `/moveTablet`

> `/moveTablet?tablet=name&group=2` This endpoint can be used to move a tablet to a group. Zero already does shard rebalancing every 8 mins, this endpoint can be used to force move a tablet.  
> [Self-managed cluster - Deploy](https://dgraph.io/docs/deploy/#more-about-dgraph-zero)

But after moving it, Dgraph can reallocate it following its internal rules of balancing data.
