Is it possible to consolidate 2 or more items on an Invoice as one line item on an Invoice pdf?

That is certainly possible with advanced pdf templates.

Can you share a sample code? Thank you!

@Luis here's an example of grouping items in an invoice. You can do something similar to consolidate but just only print the total lines. https://gist.github.com/michoelchaikin/0cbe70c350e6078a356b516bc4f8ab38

Thank you!
