WANPPPConnection virtual parameters

Good morning everyone, whoever can help me will be very grateful.

Is there any way to unify the InternetGatewayDevice.WANDevice.1.WANConnectionDevice..WANPPPConnection.. ?

Because some end up with .1, others .2, I tried to deal with various ways but without success, I used virtual parameters for some cases but the whole WANPPPConnection tree didn’t.

If anyone can help me, I appreciate it.
