Can esxi hot add memory using vim-cmd?

I've got HotAdd set to true and a bit less memory than I wanted allocated to a VM. I've got this in the vmx file:

memsize = "192"

mem.hotadd = "TRUE"

But, I've cut out my legs to get on the vcenter console of this esxi server (barring lots of port forwards), is there a way to change the memory size with vim-cmd. I didn't see anything obvious, I think I can edit the vmx file and restart the vm, but since I'm logged on to the console of the esxi server through the VM, I don't really want to do that!

So, is there a way to change memory or "hot reload" settings using vim-cmd?
