Is it possible to add bullet in the post titles?

Hello everyone,

I would like to know if it is possible to automatically insert a bullet in the filtering of posts presented in the CV?
Explaining better, what I did at first was …:
. I created some posts to have visualization and in the filters I selected “post”, in the taxonomy “Category” and in it the category that would be shown;
. Then I marked the display in GRID, one item per line and Show Title
. I deselected Show Thumbnail, Show Content and Show Meta Fields.

The result was what I wanted. A simple list, with no thumbnail, no text summary or anything. Just the title. But I was wondering if I can automatically add a bullet to each of these titles that are filtered by the plugin, without having to do this for example, in the post title.

Is there a way to do this?

Thanks
