Single Avalon-MM Master to Muliple Avalon-MM Slaves

I'm trying to connect multiple Avalon-MM slaves to a single Avalon-MM Master. I realize this essentially automatic using Qsys, if you're IP is defined as modules in Qsys. But all of my IP is already defined in VHDL and because of my build process, I can't (easily) create wrappers to import them into Qsys. I thought I could get Qsys to create a custom Ip (.qsys) module, but I can't figure out how to export Avalon-MM ports without attached IP. I'd happy to use a freestanding solution, if that were available. Any suggestions would be appreciated.

    This is a large multinational development project with many contributors. Architectural control is from a central development organization in Switzerland. To simplify integration, interfaces are defined using standards such as Avalon-MM. Trying to coordinate many different groups using a single QSYS module is not practical.
