volume pricing

[bracketsracket]

hi i would like to do the volume pricing but not for 2, 3 and 4. Is there a way to change the numbers to like 8, 16, 24 and 25+.   I am trying to keep the question simple but if i need more details please let me know.  Please and thank you in advance.

I do not think so, what you could do if variations are allow in the category is set up variations for whatever lot size that you want to sell.
