customise autogenerate icon

In the VI package buider in the 'Palettes' section you have the possibility to edit the icons.
It would be very useful if besides 'edit icon' and 'autogenerate icon' there would be an option to change the way the icon autogeneration happens.
For example in the LabVIEW icon editor, if you choose a template (which can be fully customised) which has a header, than the text entered in the icon editor is automatically placed under the header. Options like this, and also some other clever ways to cusomise the autogeneration of icons would make the customisation easier.
