Dynamic price markup plugin (non-destructive)

Hi is there a villatheme plugin to dynamically markup all product prices or a category of product prices non-destructively/virtually
For example:
Markup all prices 20% commission fees
Markup 3.6% paypal sellers fee
Markup 5.0% price increase
Each markup is additive and labeled in the admin
But on the frontend the customer should only see the dynamic totals in the shop, product, cart and checkout
Thanks Dave
