Forcing index to be created/realocated in/to specific data dir

I have ES nodes in ec2 with both with local ephemeral SSD disks and large
EBS disks
New indexes are created on daily basis.
I want current day index to be created and on SSD disks
with number_of_replicas = 1
Once the day ends i want to move the index to EBS disks and change
the number_of_replicas to 0

I could not find a feature to choose specific data dir for index shards at
http://www.elasticsearch.org/guide/en/elasticsearch/reference/current/indices-update-settings.html
I know i can move index shards to different nodes (and control number of
shards per node
) with index.routing.allocation.*, so I was wondering i can also control in
which data dir within same node index shard will be created and realocated?

tnx
