Add customer field to Cost center list KS13

Hello experts,

I'm trying to display a Z field in transaction KS13.

I've already added mi z field to the structure CSKS_CI so I can show the field in this transaction, althought this is empty.

I've tried to use for this porpuse the enhancement COOMKS01 but this only wokrs with KS01, KS02 and KS03.

Are there any way to do this?

Thanks for all!
