My application uses the default 'new', 'edit', 'delete' etc. icons in all forms. Now my client gave me a set of new icons which they want instead of the default icons. Normally I would delete the original icon and replace it (with the same name) with the new icon. This way they are all change to the new icon. But..... I can't delete and add system icons. please don't tell me I have to manually change like 700 icons in 300 forms.
