SSRS - How to set a field to a fixed position

Hello,

I am trying to display text on an SSRS report in a fixed position, regardless of the content above it. The problem is the content above may be one to three lines. As the above content fluctuates, so does the beginning of the next row of content. This happens in two places on the report.

In other words, I need two static starting points for dynamic content. I am printing text onto a pre-designed invoice that doesn't contain any customer data. The invoice is just a template (or shell if you will) and I am to position the data to print into spaces provided on that invoice.

Please see attachments. The attachment with two rows in each field is lining up correctly. I have done this intentionally as a basis. As you can see on the other two attachments, with either one or three rows, the content isn't lining up where it should be due to more or less content than my basis.

I have toyed around with cangrow canshrink but couldn't get the results as desired.

Appreciate the help!
