Dynamic Operation in Invoke activity

Question

Hi All,
We have developed a java webservice name (ShippingUtil), In this we have exposed a number of methods like
1) UpdateShipmentDetails
2) FetchShipmentDetails
3) IsValidShipment
now out of these IsValidShipment and FetchShipmentDetails both expect ShipmentId as payload.
Our requirement is such that we want to call both of them using the same invoke activity.
Currently when we call the ShippingUtil service using invoke activity we need to select one of the exposed methods. So my question is that Is there a way so that we need not define the process in invoke activity at design time, rather we should be able to call any one of the methods based on certain parameter at runtime.For this we do not want to use a switch case. Please point me to any information for this scenario.
Thanks in advance.

On second thought perhaps a better approach to sending 2 different inputs would be to define a parent input message format that contains both the input messages within, something like below and populate the right part depending on which partner link you want to invoke.
<element name="loanApplication" type="s1:LoanApplicationType"/>
<complexType name="LoanApplicationType">
<choice minOccurs="1" maxOccurs="1">
<element name="AmericanLoanApplication" type="s1:AmLoanApplicationType"/>
<element name="StarLoanApplication" type="s1:StarLoanApplicationType"/>
</choice>
</complexType>
Of course, in your soap bindings you would need to bind the rights parts of the parent message to the right operation.
