Hi! I use DRS Affinity rules at present with DRS groups etc. My question is if it is possible to get more advanced with the DRS group management? Is there any way to group VM's together based on (tags for example) rather than manually? So ideally I could get to a stage where I can mark a large number of VM's in some way (tag/naming convention etc) and have them part of a DRS group.
The objective is to tie large numbers of VM's to certain hosts for license reasons, so I'm sure this has been done before. Obviously a separate cluster would do the job but not the most efficient use of resources. I'm looking for a type of soft-partitioning almost (in software!) 
Any thoughts or suggestions would be greatly appreciated as always!
Thanks and regards
Steve
