I use projects for keeping track of expenses and profit for certain projects. however, when i am creating an invoice for a project, it goes to the 2nd line item of the invoice. i want this to appear at the top, so i move it at the top of the list. but when i am manually adding additional line items that are in addition of project (not related to the project itself), the added line item still goes to the top of the list whenever i save the invoice. is there anyway that this can be sorted out so that the project is always at the top, and the additional line items are below?
