Invoice approval conditions based on combination of multiple segments

Summary

Invoice Approval Rules need to be based on combination of multiple segments on an invoice

Content

How can we create a single condition based on a combination of multiple segments e.g. Balancing Segment ,Cost center Segment on an Invoice to find the approver? . 

 

e.g. 

There are three balancing segments 

1) ABC

2) MNO

3) XYZ and

two cost centers

1)  CC1 and  2) CC2

The rule should be able to  route to approvers based on the combination of Balancing Segment and Cost Center. 

 

if balancing segment and Cost center combination are as follows then route to different  approvers

e.g. 

if ABC-CC1 then route  to Approver1
