Fast price changer improvement

mostly of the time a product has:
MSRP price

"OUR" price usually discounted of a %

now fast price changer give me the option to modify many prices at a time, but working on the OUR price.

but if i want modify many price, changing them the % discount ti si very complicated calculation to obtain the new % from the already discounted % OUR price.

a great option could be, modify many price of a % but starting from MSRP

example:

MSRP PRICE:100

OUR PRICE: 80 (20% discount)

now i want to set many prices at a time at 30% discount of the MSRP price...

with the current situation i must take the calculator and define what is the % to move from 20% to 30% discount, and i must reduce OUR PRICE of a 12.5% to set it to 30% discount.

could be much easier to simply reduce MSRP of 30%.....

sorry for my cheap english.... hope you understand

This shouldn't be too difficult.  I added it to the dev list.  Look for it in the next update around the middle of next week.

P.s. Your English is very good.

another thing, related to fast price changer but also other tasks.

it is a "since ever" x-cart problem, so you MUST be better :-)

IMPROVE the management of products "by BRANDS" you are mainly focused everywhere by "category"

if i need to change prices of a entire brand to push it (for me more frequent than changing an entire category)i can't use fast price changer

question:

Fast Price Changer works also on attributes surcharge if exist?
