cauatc, I don't know, but I think that if you are operating to Cat 1, you shouldn't need to.
But it may be advisable to inform the pilot of your current status (Cat1, or whatever it is.) I would hope the crew would be aware of that in any case.
Refer to what your unit documentation states concerning differing procedures with any category change. For example, ours has a brief list of the weather criteria that requires a change, and which holding points to use (or rather, which not to use) and protection area needed.
