Can custom value set used in account hierarchy at account segment level?

Content

Business would like to know if we can use custom values set. This custom value set stores values  (size up to 30) larger than the size of the account segment (size 7). Custom value set store the parent values. I created Hierarchy but value in parent values does not show any values. Had anyone handled this kind of scenario?

 

Thanks
