An aspect of the present disclosure provides for applying hot fixes to metadata customizing user interactions based on a software program. In an embodiment, a hot fix containing new files is received. Each new file contains a corresponding modified metadata. The user is presented for selection, differences between each new file and a corresponding existing file. Only the selected differences are then used to form patched files, which thereafter control the user interactions, for example, by replacing the corresponding existing file with the patched file. Accordingly the user is provided enhanced control over which of the differences is applied to the metadata.
