Garry's Mod - Change gamemode tag?

[dev02ify]

When you want to isolate a certain gamemode in the legacy browser, you can use the tags section.

The tag for spacebuild2 is gm:spacebuild2
Now with my server, it's different and displays as just spacebuild.

The problem is, the normal server browser also uses tags to isolate the gamemodes, so my server isn't listed under spacebuild2.

I've looked in the gamemode files with ctrl + F but found nothing. I checked the server cfg. sv_tags isn't recognized in the gmod console.

Windows 7
Garry's mod

Code:

@echo off
cd c:\srcds\orangebox
echo Starting game server.
echo Beginning "Garry's Mod"
srcds.exe -console -game garrysmod +map gm_construct +maxplayers 16 -ip 0.0.0.0
echo "Garry's Mod" has now started.

I don't think computer specs will help with solving this problem...
