Bulk edit prices with advanced pricing for quantity discounts?

Hey all! I am begging the souls of reddit to help me save hundreds of hours of tedious work.

For context, I work at a trophy shop that uses Magento for our ecommerce website. We are in the process of updating the price of all our medals. We have hundreds of styles of medals, and each style comes in multiple sports/reasons/places – so it’s thousands of individual listings to change. The pricing on these is one price for a single item, then there’s breaks for 10, 50, 100, etc.

I am looking for a way to bulk edit pricing because each style of medal costs the same, so rather than going into 20 or so products that all have the same price breaks and repeating it over and over, there must be a way to select multiple products and update the pricing at once?! I know from the Products page I can select multiple items, then Update Attributes, and price is one attribute I can alter for multiple at once, but it’s ONLY the single piece price, it doesn’t have the option for advanced pricing with the quantity discounts.

I cannot be the only one who needs this functionality, so I figure I must be missing something. I have NO formal Magento training, just what I’ve taught myself from good old google, but I’m basically solely responsible for maintaining this website. Being able to change prices like this would save me so much work. :}
