discount pricing by manufacturer

in oscommerce there was a hack that you could use. basically you could load up all the products via mfg by a drop down button.

all the products would list

each product would have three fields
your current price | your sale price | and the third field would show the dicount in percentage

now you could enter a percentage like 5% off and hit enter and all the products for that mfg would be 5% off.

or you could do each product on the page separately.

is there a modiciation for that anywhere? i did not see it or is it built into zen cart.

i looked at admin > catalog > specials but i dont think that is rigth.

here is the contribution

Did you try the price manager?

Yes, can you give me step by step how you do it?

Seriously with all the features of ZC I can't believe this is impossible.

some zc guru has gotta have this in the works!
