How to Apply a 2% Increase to Trade Prices in InDesign Catalogue?

Hi all, I have a product catalogue - https://indd.adobe.com/view/5fdb11c8-8c8f-4346-853a-840085184228

I need to increase the Trade prices throughout by 2%.

I have a style sheet set up whereas I can target just the Trade price (leaving the RRP alone).

Is there a plugin or script that will allow me to do this?

I have been using Price Adjuster  2025 for currency conversions but I don't think this plug in will allow me to increase by percentages. 

Many thanks for your help
