sysOverallcustom1 and sysOverallcustom2 in Succession org chart

[S0020073676]

Hi,

We have configured sysOverallcustom1 and sysOverallcustom2 because we want 2 extra ratings besides the regular Performance, Potential, Competency and Objectives. 

We would like to do an initial import on these 2 trend elements, and them to fill them in People Profile.

I added the blocks in People Profile but I see it is picking up all the overall ratings available in the system (Performance, Potential, Competency).  Anyone knows how do I mention what the rating scale should be for these 2 custom ratings and how do I stop them from picking up other ratings?

Thanks in advance
