How do I share multiple networks with windows 7 Virtual Wireless Network?

Background:

While I am at school, I often take my lunch time to play some games online. The school's network blocks most of the game auth servers, but the servers I coect to to actually play on are not blocked. In order to authenticate with the games I set up my computer's routing tables (using route in the command prompt) to direct traffic to the blocked auth server through my phone's slower, limited data hotspot coection, and all traffic to the game server through the school's low latency network. This all works.

Separately, in the past, if I've wanted to host a virtual wireless network from my laptop to share one of the other networks I'm coected to (ex. a wired coection), I would go to my interface settings (Control Panel -> Network and Inteet -> Network Coections), open the properties dialog for the interface I want to share, enable sharing and choose the network I want to share it with (Virtual Wireless Network Coection) and run the command netsh wlan start hostednetwork from the command line to host the other network's coection using my laptop's wireless. This also all works.

Now for the question: How do I share both my wired and hotspot coections over the virtual wireless network so that others can take advantage of my rerouted network without having to set anything up themselves?

I can't open the other network's Properties dialog and enable sharing on it as well because windows only allows one network to be shared (or at least implies such by saying "[Sharing] will now be enabled for [secondary network] instead." whenever I click the checkbox to enable network sharing).
