Hello All!
If you look at player statistic of competition there are 5 columns: Rank, Player name, Nationality, Team and changable stat.

Is it possible to add AGE and POSTION columns to that screen?
I`ve tried to change competition player stats.xml but nothing happened. I only get empty columns AGE and POSITION by adding :

<record text="Age" alignment="left,centre_y"/>
<record text="Position" aligment="left,centre_y"/>

but also i guess i need to make add lines with <record indx.....> for Postion and Age like
<record indx="2" id="natc" sort_disabled="true"/> for nationality
