So presumably the IP protocol rider protocol has fields of its own.
Does the IP protocol rider have an IP protocol number assigned to it, so that you have:
link-layer protocol
IP, with the IP protocol number having the value for the IP protocol rider protocol
IP protocol rider protocol
custom protocol
some protocol that normally runs directly atop IP
or is this a non-standard encapsulation where you have:
link-layer protocol
IP, with the IP protocol number having the value for the protocol that's above the custom protocol
IP protocol rider protocol
custom protocol
some protocol that normally runs directly atop IP
The former can be done without modifying Wireshark, but not the way you're doing it.
The latter *CANNOT* be done without Wireshark's IP dissector to directly call the dissector for the IP protocol rider protocol.
