vSphere VMID overwritten from template

Hi.

i've used vSphere Synchroniser to initially bring in all our VMs, then I choose to rename and move some out into a subfolder for important VMs.

I've saved one as a template and changed the Custom Image, and blanked the VMID in the template.

Now when I apply the template to all the VMs (Edit > Special Actions > Convert from Template), it deletes the VMID from the VM session entries
as the value is blank in the template.

Is there a way to prevent overwriting certain properties that are specific to entry types - I know we can "keep" the name, image, description, etc etc when we apply the template, but VMID isn't one of the options to keep as it's configured within the entry type.

Screenshots in order show the progression from working VM (from the synchroniser) to non-working VM once the template is applied.
