How to Manage Dynamic Content Lengths in Dynamics 365 Document Templates?

I’m using an agreement template in Dynamics 365 Online and have configured data mapping to populate fields from CRM into the template. However, some fields have variable lengths—for example, a value could be 10 characters in one record and 100 characters in another. Similarly, certain address fields (such as Address Line 2) may or may not contain data. I’m currently using text tags to insert these values, but I’m struggling with layout and formatting. Adding extra whitespace to accommodate longer values doesn't seem like a good solution, while leaving it out causes the text to truncate or disrupt the document formatting. What is the recommended approach for handling variable-length and optional fields in agreement templates? Any best practices or suggestions would be appreciated.
