Best practice should be to apply sorting and part numebrs to parts from the bill of materials window.
Setting should be able to be applied to this (filter and renumber) as default on a template.
Sub titles could also be inserted which do not have an impact on the bom but allow better catagorisation of parts in the bom.
This would allow for better automated export of BOMs into ERP systems
This should also all be able to be controled by ilogic.
