need help on N value display "greater then"

Hi everyone.
I was inputting data on the N value under data tap, and I come across a data ">50"  or "50+" does anyone know what ways to input this data so that it will show higher than 50 on a sample?
Right now doesn't matter what I put it. That is other then a number or "WR" it will become blank.

so far the only way I know to go around this is to edit the PDF file after the borehole log is complete.
