context - high performance private cloud with cpu pinning

Is it possible to map vCPUs to specific pCPUs ?
Currently I see you can only direct which vCPUs are mapped to a specific
NUMA node

hw:numa_cpus.0=1,2,3,4

However, to get even more granular, is it possible to create a flavor which
maps vCPU to specific pCPU within a numa node ?

Something like:
hw:numa_cpus.<NUMA-NODE>-<pCPU>=<vCPU>

hw:numa_cpus.0-1=1
hw:numa_cpus.0-2=2


Thanks!
