Multiple Maps in single orchestration

I have to map different HL7 schema to different outbound xml body schemas. 
Each output Body schema having different fields depending on Input.
 Suppose ADT_A03_231_GLO_DEF.xsd  to ADT_A03_231_Body.xsd.
                ADT_A03_23_GLO_DEF.xsd  to ADT_A03_23_Body.xsd
                ADT_A08_24_GLO_DEF.xsd  to ADT_A08_24_Body.xsd  
                               … Etc.
My input file (HL7 Message) always from one input ****t (MLLP Adapter) and
I 
have to send Output file (XML) to one ePayment site (web services).I
design 
one orchestration with one receive ****t ,one transform shape(for maping)
and  
one send ****t, it’s working fine.

 Now my question is how to implement this orchestration for multiple 
maps???. Depending on input file it map to related output Body schema and 
send output XML to web services.

Please give me solution for this problem.
