Schema-based sharding distribution strategy.

Citus allows to customize the distribution strategy of shards by defining custom re-balance strategies, for instance moving a schema to a specific shard and giving weightage to specific nodes in node_capacity functions. But I have to trigger a rebalance frequently.

Is it possible to **define a strategy during distribution time itself**? whether this kind of feature already exists in citus.
