Use percentage in price tiers

Can be the price tiers be calculated in percentage?

I think this is necessary because if I have several product levels, I would need to calculate the tiers not with a natural number but with some fraction or percentage.

example if I have the “Test Product”

with the price levels “high”= 500$ “med”= 200$ “low” = 100$ and the price tier is 5$ for 10+ products, is not representative. Instead of 20% of discount that is flexible to each price level.

BTW Sorry for my english
