Entering multiple/same fixed assets

Hello,

i am setting up a company file for a party rental business.  I purchased 2019 QuickBooks Pro for the desktop. Customers/AR is all done.  I do have an issue on the AP side of entries.  I need to add the start up expenses, which I would think would be fixed assets that would depreciate over the next few years.  Party tents have been purchased, but multiples of the same sizes, i.e.:  2 each of 10 x 20 tents, 10 x 30 tents, etc.  I created a fixed asset main account of tents, then a sub account fixed asset of each size.  I also created a fixed asset item list for each specific size.  When I went to create a purchase order for the initial purchase of 2 10 x 20 party tents, and 3 10 x 30 party tents, the qty field in the purchase order prepopulates to only quantity 1.  I have found no where to adjust this quantity.  Why is this?  Why can’t I enter the quantity purchased as they truly are fixed asset?
