Using library 'alike' approach with 4GL P-code

Hello, Does anybody know if a library like approach can be applied if you use 4GL P-code. What I want to achieve is to put all kind of universal functions in a module-file and distribute this module-file as a separate part. At the moment I have the situation that the module-file with the universal functions is concatenated with several main-module files; this yields a program. This is the common approach. But what if 50+ of such programs occur and some function in the universal module must be modified. Then all 50+ programs have to be distributed to my customers (which are more than 50). Any help or suggestions would be greatly appreciated. Regards, Henk
