MQTT subscription return numeric Value of "devider/values"?

[ostauss]

Dear all,
i currently have a problem with the result of a MQTT (json) topic subscription (in node-red).

I want to "read" the numeric value with MQTT from the follwing Attribute (15.f37.csv):
r;w,,Hc1SFMode,HC1_SFMode,,,,"5D00",,,UCH,0=none;1=party;2=onedaybankholiday;3=onedayholiday;4=holiday;5=bankholiday;6=quickveto;7=onetimeventilation;8=onetimewater,,activated special function of first heating circuit

As you see does the configuration define Stribg values for numeric output (0=none).
For example from HTTP i receive this:

    ....
    "Hc1SFMode": {
    "name": "Hc1SFMode",
    "passive": false,
    "write": false,
    "lastup": 1666169280,
    "zz": 21, "comment": "HC1_SFMode",
    "fields": {
     "0": {"name": "", "value": {"value":3,"name":"onedayholiday"}, "comment": "activated special function of first heating circuit"}
    }
    ....

This is OK. as you see i receive the numeric "key" and the string "value".

On MQTT i receive this:

{
	"topic": "ebusd/f37/Hc1SFMode",
	"payload": {
		"0": {
			"name": "",
			"value": "onedayholiday",
			"comment": "activated special function of first heating circuit"
		}
	}
}

Question:
Is there a option / Setting / Parameter to enable the numeric keys on MQTT subscription results?

Thanks in advance
Oliver
