Hello. Not sure if this is where I should post this. We are using NS standard Promotions. We want to create a promotion that gives 10% discount if the quantity of the item is 4 or fewer and 25% if it is 5 or more. Is there a way to handle this withing 1 promotion?

No, you have to apply the promotion based on the quantity. Both basically are different promotions one will be 10% off and another is 25% off. Quantity is just a criteria in your use case to select the promotion.

Correct. Thank you
