Analysis Office 2.2 excel formula

Hi, all

I'm trying to create a simple workbook with "excel formula" new feature of AO 2.2.

It works pretty great except one thing. If I use KEY+TEXT displaying for my characteristic in rows, I can't create the same for new inserted row with formula. The thing is I can only put some description to KEY cell. When trying to put some text to the 2nd descr cell the systems automatically move this text to KEY cell.

I need it like this:

Has anyone idea how to use both field KEY+TEXT for additional calculated row?

Thanks in advance.
