Can volume definitions point to a unique path per indexer in an indexer cluster?

Hi, 

I have a question related to defining volumes especially the coldvolume in our case. 
I want to point the coldvolume to a unique location on network attached storage. 

Example we have 3 indexers with the following hostnames
idx01
idx02
idx03

say we have a local mount point on every indexer which points to the NAS mynas

/mnt/coldvolume -> nfs://mynas

Option 1
Can I then define a volume in /etc/system/local/indexes.conf on every indexer. 

On idx01:
[volume:coldvolume]
path = /mnt/coldvolume/idx01/

On idx02
[volume:coldvolume]
path = /mnt/coldvolume/idx02/

On idx03
[volume:coldvolume]
path = /mnt/coldvolume/idx03/

The indexes that are then distributed to all indexers in this cluster are of the format 
[myniceindex]
coldPath = volume:coldvolume/myniceindex/colddb

Option 2
As an alternative I can also mount to the subfolders on the NAS
by modifying /etc/fstab and letting the /mnt/coldvolume point to nfs://mynas/idx{01,02,03}

I can then distribute the volume definition to all 3 indexers like this
[volume:coldvolume]
path = /mnt/coldvolume/

Question: Is option 1 a valid / supported configuration for a Splunk indexer cluster?
Question: Or is option 2 the best practice?

Option 1 is out because all indexers in a cluster must have the same config.

Option 2 is out because NFS is Not For Splunk (but may work if performance is up to spec).
