plugin

Hello, I state that I have recently arrived in the wordpress world, I am building a site with woocomerce, I would like to know if there is a plugin that allows you to insert a module with a message inside to insert within the products, I give an example I have to communicate with only some products that I can offer the service of delivery with assembly so to speed up I write the communication and it is displayed simultaneously on all the products of that category.
I hope I was clear .

Greetings
