I did plugin Import Manager 2.0 for import products, categories, manufacturers.

You have two solutions.
1. Purchase external plugin, example my plugin
ttps://www.foxnetsoft.com/noprichcards.

2. Add new markup in cshtml files. See how nop team added existing markup for price, breadcrumbs, etc.

I have other plugin Automatic Update (prices and stock quantities)
https://www.nopcommerce.com/automatic-update-prices-and-stock-quantities

You can do it easy.

This first plugin allows to import/update products, categories, etc.

Popup Manager  

Plugin allows you to add popup window on any pages using difference conditions, ex. on Home page, product details page.

Features:  
1. Add popup window on Home page, all pages, Login page, Register page, Category, Manufacturer and Product details pages using different conditions.
Example.
Add the popup window on Home page about New Year discounts in your store.
Add the popup window on Product details page that this product has Free Shipping.
2. Support start and end of the date of showing popup window.
3. Support multilanguages
4. Support multistores

Compatible for NopCommerce 4.20.
