How to automate the insertion of the same html code in the description of each item for sale?

Hi everyone,
I would like to ask how I can insert the same snippet of static html code on all the items I have for sale.
For example, if I want to insert the same description that must be the same for each item on sale, it is a bit cumbersome to change the items one at a time.
How do you do it?


Unfortunately, although this is a much requested feature, there is no direct way to do that.
You can however use a Chrome extension dedicated to this. I don’t remember what it was called though.

It would already be something, better than nothing. If anyone knows the name of this extension could write it in this post, so I try it.

I think it was this one:


Thanks PurpleFog. I will try this extension, hoping it will work.
