Adding a single ePMP MIR profile with cnMaestro

Different AP’s (2.4Ghz 5Ghz N 5Ghz AC ) and different types have have different profiles but I would like to add a profile to all in addition to whatever profiles they already have.

I have tried -

{
	"template_props": {
		"wirelessMIRProfileTable": [
		  {
			"wirelessMIRProfileNumber":	"10",
			"wirelessMIRProfileDescription":	"10Mbps",
			"wirelessDLMIR":	"11500",
			"wirelessULMIR":	"11500"
		  }
		],
	}
}

But it says must at least contain default -

{
  "device_props": {
    "wirelessMIRProfileTable": [
      {
        "wirelessMIRProfileNumber":"The default profile should be present" 
      }
    ]
}

I’m concerned that if I add the default 0 profile then the AP will end up with just the default and this 10Mb profile and remove all the others. I simply want to insert 1 profile.

I also tried -

{
    "device_props": {
        "wirelessMIRProfileNumber":	"10",
        "wirelessMIRProfileDescription":	"10Mbps",
        "wirelessDLMIR":	"11500",
        "wirelessULMIR":	"11500"
    }
}

And it reports that it was completed successfully but the profile does not show up on the AP.

Is it possible to just add a profile to all the already existing profiles on an AP ?
