How to add multiple and identical POs?

How to add multiple and identical POs?

HI, I'm trying ServiceDesk Plus before purchase a license.

I am trying with some data on my company and I have 13 budgets exactly the same but with different billing info and those budgets are very detailed. Here an example to better understand:

Budget 1 for Company 1
keyboard 20$
mouse 20$
license 200$
screen monitor 100$
software 500$
Bank Addon 100$
Selfcards Addon 100$
Barcode reader 10$

Budget 2 for Company 2
keyboard 20$
mouse 20$
license 200$
screen monitor 100$
software 500$
Bank Addon 100$
Selfcards Addon 100$
Barcode reader 10$

Budget 3 for Company 3
keyboard 20$
mouse 20$
license 200$
screen monitor 100$
software 500$
Bank Addon 100$
Selfcards Addon 100$
Barcode reader 10$

....

Budget 13 for Company 13
keyboard 20$
mouse 20$
license 200$
screen monitor 100$
software 500$
Bank Addon 100$
Selfcards Addon 100$
Barcode reader 10$

When a Budget is very large, Its very tedious to insert just one Budget, so introduce 13 identical budgets are very extreme time consuming.

I created a PO, and added those items as "Others" Category, as I think if I add as "Asset" Category is nonsense because I should not waste 1 asset for an addon (if I buy the 250 limit assets license, for me there is no sense if I consume 20 assets insertings Addons for a specific software). So, add all of that was very time consumpting for one budget. Now, I have added the first budget, there are 12 left. I created another PO and add again the same articles lines.... 

My concern is, how can I optimize this labor? I am doing something wrong? Can I duplicate a PO and then change its billing info? How do you manage this?

Thanks in advance
