SWIFT - Complex par file

We are implementing FileAct file transfer to SWIFT Network trough SAP Integration Package for SWIFT, we have sucessful configured all the objects in integration builder and the system is generating payload and parfile, but the par file only have a RequestType element inside overrides section. In our case banks are requesting a more complex par file, so we need to add more elements and values to par file. Is this posible using Integration Package for SWIFT?

The system is generating par file in this way:

<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<Parameters xmlns="urn:swift:sag:xsd:fta.param.1.0">
<Overrides>
<RequestType>pain.fin.mt101</RequestType>
</Overrides>
</Parameters>

We are needing the par file in this way:
