Is there a way to include the Deposit Applied amount on a Sales Order form (SFM)?

SUGGESTED

I wish to customize the Sales Order form (SFM) to include the amount of the Deposit Applied when printing a sales order. If I am not mistaken the insert data field does not include that field.

Ideally I would also like to to show the sales order amount net of the deposit applied. 

Does anyone have any ideas?

Thanks in advance
