since you are not maintaining all the described components as separate inventories, why not provide a simple description mentioning the annexure number which can be included as attachments to the quote.
Because the qty and line item from manufacturer are separating in line as what I did and I am matching 100% the same else the customer will not accept it. Will there be patch to fix this issue ?

A suggestion - create the multi page invoice using a word processing document, and just enter summary in Manager
