MinerOptionsPackage.json for phoenix miner, doesnt work

[tf-Druse]

I want to Overclock my cards through the phoenix command line settings eg. -cclock settings. I tried following the posted instructions to change MinerOptionsPackage.json settings, however when I run nicehash as admin, the settings I change inside the MinerOptionsPackage.json do not apply.

I changed "use_user_settings": true,

"type": "OptionWithMultipleParameters",

"id": "phoenix_gt",

"short_name": "-gt",

"long_name": null,

"default_value": "-gt 31",

"delimiter": "null"
also tried
"type": "OptionWithMultipleParameters",

"id": "phoenix_gt",

"short_name": "-gt",

"long_name": null,

"default_value": "31",

I set the -gt option, and I know its not working, because it still tries to tune all my gpus. Please advise, thanks
