Currently, Custom Reports does not feature its own segment editor, but any segments defined in Analytics will automatically become available for use in Custom Reports.
All filters and conditions supported in segments by Analytics are also supported by Custom Reports. For guides on how to create Analytics segments, please consult Analytics documentation.
After changing segment definition in Analytics, you need to refresh the page or re-pick the segment to see the changes in Custom Reports.
