Hi all,
I've searched the forums and the internet in general, but I haven't found an answer to this. Though it might just be that terms that I am using in my search are too broad.

Anyway, I would like to cap the quantity available for each item displayed at a maximum of 4.

So, so say I have 50 different product listings. For each product I have 1 to 30 in stock depending on the item. Is there a way for ZenCart to continue to keep track of inventory but to only display to the customer that I have a maximum of 4 of each item available?

To put this another way:

Lets say that I have the following items in stock:

Item A : 11 units in stock
Item B : 3 units in stock
Item C: 22 units in stock
Item D: 5 units in stock
Item E: 4 units in stock
Item F: 1 unit in stock

It would be ideal for me if, when a customer looked at the product listings and product info, the quantity displayed looked like the following:

Item A : 4 units in stock
Item B : 3 units in stock
Item C : 4 units in stock
Item D : 4 units in stock
Item E : 4 units in stock
Item F : 1 unit in stock


I want to set (or cap) the quantity displayed for each item at 4.

Hopefully this question makes sense.
Thanks in advance to anyone who can help shed some light on this.
