Update Quote Pricing

Update Quote Pricing

So currently we use both Books and CRM.  From Books we create and update pricing of our items and sync to the CRM.  We are trying to find out a way to create a button that would update the pricing on the products in the quote.  

The specific problem is:
We create a quote on 11/1/19 that has 3 items on the quote.  Then the customer comes back in 3/1/20 to check the pricing, our quotes are only valid for 60 days.  Some prices might have been updated in items/products, but the only way to update the price or description is to delete the product and add it again.
