How to add a link with dynamic data and a custom label?

For example: If I have an acf field for a pdf file, I would like to create the link to it but with a custom label.

Right now what I have done is {acf_my_file:link:newTab} which renders the following:

<a href="https://domain.com/wp-content/uploads/my_file.pdf" target="_blank">
File Title
</a>

What I would like is:

<a href="https://domain.com/wp-content/uploads/my_file.pdf" target="_blank">
CUSTOM TEXT
</a>

Have you considered using another text-type field for your link text and using that for a Button or text link?
