Avoid repeated authorization dialogs when changing network settings

I have an swift command line tool that changes proxy settings in system preferences via SystemConfiguration framework, does some stuff, and in the end reverts proxy settings back to original.

Here is simplified code:

var authorization: AuthorizationRef?
let status = AuthorizationCreate(nil, nil, [], &authorization)

let prefs = SCPreferencesCreateWithAuthorization(nil, "myapp" as CFString, nil, authorization)
// change proxy setttings

// do some stuff

let prefs2 = SCPreferencesCreateWithAuthorization(nil, "myapp" as CFString, nil, authorization)
// change proxy settings back to original

When I try to change settings for the first time, the system dialog appears requesting permission to change network settings. If I try to change settings again within а short period of time, the dialog does not appear again. However, if it takes more than several minutes after first change, the dialog does appear again. Is there a way to create authorization, so that the dialog appears only once per app launch, no matter how much time passed since the first dialog?
