E1 Approval Route Code without Order Type

Hi,

As i have a requirement where i need to set up approval route code based each Department in the company.

For Example -

IT           - APIT

FIN        - APFIN

MFG      - APMFG

Etc

Along with this i have several purchase order type. For each order type i need to create the above approval route codes.

As there are several order types & department, there will be several Approval Route codes. May be count of 50 plus.

So is there any way if we can create only 3 approval route code for above Department example & it will get attached to user profile.
