Is there any way to increase/decrease the price of all attributes by a percentage easily?

[KubitDesign]

Hi All,

 

I have a question about increasing/decreasing the price of ALL of my attributes on my site.

 

I have created an online computer store for a client, and we are using the 'Attribute wizard Pro' module from Tomer (Presto changeo) to add upgrades to computer systems (processors, motherboards...)

 

However my client has informed me that the price of these upgrade parts fluctuates quite frequently and therefore we would need to make adjustments to the prices of these attributes every so often. Now considering that we have say, at the moment 15-20 computer systems each with around 40-50 attribute upgrade options each, is there an easy way to update the prices of these attributes as a whole, by percentage, instead of manually changing the price of each attribute for every product!?

 

I appreciate any help with this problem,

 

Many thanks,

 

Steve.
