Repeat regions on a manufacturing draw

Hello,

On my manufacturing draws, i have a sheet for each operation (op010, 020, 030 etc.)

On each sheet i have a repeat region with all sequences type, name and tool for the actual operation.

I order to simplify the operatior work, i would like to add a fifth column with the tool_pocket_number for loading the tool carousel on the machine with the right tool.

Here are my column parameters :

When i add &mfg.actoper.workcell.head.tooltbl.toolpocket.tool_position in the fifth column here is what i get :

How can i add for each line the tool pocket number ?

Thanks in advance.
