@PedrooT were you able to find a solution for this? 

To add a solution to this issue:

You can create the document custom field & add to the word template with the AutoPlace Text format \text_{r}\. In your testing, you need to be able to preview before send.

In the preview, you are able to open the settings of the custom merge field and are given more advanced options which can specify the width of the box.
