would it be possible to inherit a SF Maintenance Form so that the MaintenanceFormToolStrip would be editable using VS in the new inherited form?

The items in the form can be modified using code, but it would be nice to be able to modify the MaintenanceFormToolStrip using VS.

What I tried was 

1) create a SF Maintenance Form
2) make the "Modifier"-property "Public"
3) make a new form by inheriting from the form created in step 1

The MaintenanceFormToolStrip doesn't allow it self to be accessed. With a standard button the buttons properties are accessible.

What goes wrong here or is there a better way to achieve this?

TIA,

Kari
