Registering UDFs
 

I am using Jan Karel Pieterse's RegisterUDF class module to register 70 odd
functions in a number of categories within a custom xla add-in.
However, to keep them out of the User-Defined category I declared them as
Private.
But now I need to make the add-in able to be referenced by other projects
and so the functions need to be not private (not necessarily Public) When I
do that they appear in the User-Defined category. I could use the
MacroOptions approach but prefer the full descriptions offered by JKP's
approach.
Is there a solution to this problem ?

On a related matter we declare one function to be in the Engineering
category to avoid problems with the Analysis - VBA add-in
