How do I make a link added to text in the text element open in a new window/tab?

I have some links I placed into the text within the draggable text element. I do not want people that click on these links leaving my site.

When I open the link icon on the editing bar, there is no option to "open link in a new window" or a place I can find where I can add the
target = "blank" so the link will open in a new window/tab.

How can I fix this?

Thanks.
