authorization for every resource of wsdl

I have trouble when downloading wsdl. It have many resources on the same server. For example

wsdl.com/service?wsdl

there are links to wsdl.com/service/a.xsd, wsdl.com/service/b.xsd

And this scenario request from me 3 times basic authorization.

In version 4.0 I´m able to download this wsdl on one authorization try.

It is very disturbing because I cant use this if i have shared types and i have a lot of resource i cant use this method to create project.

Thank you for your help.
