Anchor a line in a text position, that 'links' to a text box.

Hi there.

I searched but didn't find a solution. Not sure if I'm using the right words to search or to describe what I need here.

I'm not sure if it is possible in InDesign, but I'd like to 'link' a text box to a certain word in another text box, with a line. So, one anchor of this line follows to the word, and the other one follows the box. The image bellow may help to illustrate:

Not sure if I made myself clear, and hope someone can help me.

Best,

Caio.
