Can I save a "star-hash" (*#) code as contact?

I'm developing on a Huawei phone, and to enable logging on this device one must dial *#*#2846579#*#* to get to a hidden service menu, as described in this answer on Stack Overflow . Is there any way I can save this code as a contact and "dial" it from the favourites list for easy access? Of course I tried just adding a new contact with the code as the number, but when I "dial" it the phone actually dials the number instead of opening the hidden service menu, resulting in a "Sorry, you can't dial this number" voice message from my phone operator.
