TSM Online Indexreorg with temporary allocated filesystem

High end customers using TSM with SSD for DB directories and running 7x24 are very likely to run into the following situation:
because SSD space is very expensive, it is not always possible to permanently attach hundreds of GBs to each TSM instance only for running an online index reorg for the big tables like BACKUP_OBJECTS.
Sample: customer has 20 TSM instances with each 350GB space on SSD allocated for TSM DB directories, DB usage is in average 300GB. Online index reorg is aborting with unsufficient space, because at least 80-90GB of free space in the DB directories are needed for the index reorg.
Offline reorg is not an option, because of 7x24 availability for the TSM servers.
Solution could be having a temporary filesystem (on SSD or regular disk) which can be specified for online index reorg usage and only needs to be attached to the TSM instance for running the online index reorg.
E.G:
check if index reorg is needed for big tables like BACKUP_OBJECTS
attach temporary space to specific TSM instance
setopt allowreorgindex yes
... let online index reorg run to end over all tables
setopt allowreorgindex no
detach temporary space from TSM instance and attach it to the next instance.

    Thank you for submitting this request. This is a recognized requirement and a solution appears to be desirable. This request is not in a committed release plan for this year, but the theme is aligned with our multi-year strategy, and will be a candidate for a future release. IBM’s plans may change and no commitment is made that a solution will be provided.
