Access WSDL from another project

I have created a SoapUI project that contains all the WSDLs in my software. Is there any way to refer to these WSDLs from a different project, so that if the base WSDLs change, I dont have to update all my other soapui projects. If I clone, then I will have to update wsdl definition in all my soapui projects everytime the Wsdls change.

For ex: All my WSDLs are in a project called AllWsdls.xml. I have another project that has test suites and test cases. Is there any way to create teststeps based on the Wsdls defined in AllWsdls.xml?
