Dynamic Text: Target Self

I have a few html links in a dynamic text box from a .txt file I’m importing. I’m wondering if and how I can go about having the links load in the dynamic text field instead of a new window.

In other words, I want the dynamic text field to target itself… maybe something like this in the .txt file?

<a href=“loadVariables(“link.txt”,”");">Click Me</a>

Thanks for your help!
