Not sure I totally understand but why don't you just copy and paste the numeric values between the poses? Or duplicate the pose? Feel free to send me the file and I can take a look (firstname.lastname@example.org)
In the Pose controls, turn OFF the Start At Center controller. When this option is OFF the baseline of the first line becomes the stable point, so if you change from a single line to a double line of text, the first lines will stay in register.
Also, left/right position is based on the justification setting. For instance with left justification on, the text will all match at the left corner of the top line.
If you leave Start At Center ON, the text is shifted to the current center of all text in the block. So every new block of text is going to shift.
