Apply HMR for all methods except one

Hello all,

I'm trying to apply one HMR for all methods except the ACK.

I wrote the following:

                msg-type                                request

                methods                                 BYE,CANCEL,INFO,INVITE,NOTIFY,OPTIONS,PRACK,REFER,UPDATE

          

But I'm wondering whether we can do it differently instead of listing all the methods some thing like !ACK.

Any idea ?
