VMware affinity rule

We want to use terraform to build affinity rules for a set of VMs.
This is possible with the terraform ressources “vsphere_compute_cluster_vm_affinity_rule” and “vsphere_compute_cluster_vm_group”. Indeed it is not possible to add some VMs to an existing vm-group over the resource “vsphere_compute_cluster_vm_group” to increase the vm-group.

Do you known any solution to add new VMs to an existing vm-group via terraform?
