Adding Rows To Sheets With 3D Referencing?

I have attached a file for reference. I have another file I use that is similar to the one attached, however it has 500+ rows and is still growing. The issue I am having is that in this file I want to make a "Template" worksheet. Basically I need 50ish sheets that are more or less the same. I have a column that describes a item, a items weight, a row with headers for the columns that I want to appear identical on every worksheet. I want the variables to be the count. These will change from sheet to sheet with formulas to than update the totals.

My issue I am having is that I constantly find myself needing to insert new rows for new items. In my real worksheet I have rows grouped together in a logical way so the rows cannot just always be placed in the next available row at the end of a sheet. How I can have sheet 1 be my "template" and the others take their item lists and weights from sheet 1. In the example file I created sheet 1. I than created sheet 2 and selected a cell entered "=" and selected the cell that I want it to have the same info from on sheet one. I fill handled these items down to generate a list. I than held down control and dragged a couple of new sheets. This process works, and is what I am currently doing, but what do I do when I wish to add a new rob between row 4 & 5?
