Journal Approval based on accounting segment

Summary

I would like to route journal approval for certain accounting segments to certain approvers

Content

We have a very basic journal approval currently: all journals are routed to one approval group.

I would like to add additional rules to route journals with lines on certain accounting segments to different approvers. I am not having much luck creating a rule using Journal Line Account Combination contains "XX-YYY-ZZZZ" or similar.

Can anyone advise me if it is possible to route based on accounting segment.
