I would go with a one-for-all remote, because if the menu function isn't preset via preset code, theres a good chance there is a advanced code for it.

OFA remote are the only ones that take advanced codes, these are 3 & 5 digit codes for individual functions. These are what's available for sony tvs:

Newer OFA remotes like the urc-6820, 8820, 10820 take 5 digit advanced codes, so you would need to add to zeroes to the FRONT of each in that link.
