Using Bar Codes to add sales items to an invoice and also split amounts in the General Ledger

[CabLAC]

We are a not for profit sport organisation and are wanting to use barcodes for our sign on processes. 

Our fees are discounted for multiple family members and we have a finite amount of options. We want to set a barcode to the family registration option (eg 1 Tiny Tot and 2 older kids). The Fees are made up of multiple components linked to our General Ledger (eg lighting, equipment, general fees).  We also have uniforms as separate items for sale.

Is it possible to firstly use barcodes to populute sale line items in MYOB and can these items be automatically linked to spliting the the sale income for that item to General Ledger codes?
