Too many "boxes" in PDF report while editing

Hi, I'm creating a report as PDF file (Report Builder 12.2.1.3.0).

In Paper layout there is only one field which gets some multi-line value.

When the ready file is opened with Adobe Acrobat for editing it has much more text "boxes" which makes

editing more complicated for our users (and they need to add or fix some text).

Often the "splitting" happens where the text has several empty lines.

Is it possible to avoid it and get all text in one box while editing?

Thanks in advance,

G.R.
