Could somebody advice on following situation, I want to:

• Add a button 'Load products' to Quotation form

When clicked, this opens a wizard where you can:

• Select multiple product from the list of products
• Click a button 'Add'

Is it possible to write a method on the Quotation object that adds the products selected in the form?

Would it be possible to provide some code to help me on the way? I find wizards to be very badly documented..
