Hi Bryce,
or if there is a way to point them at a single server instance of all templates (which would be ideal),
Set the file attribute to an absolute path e.g. file="H:\temp\reuben2.4rp" and ensure that all your team have the appropriate drive mapped to the same place.
For others, what I showed Bryce was user.conf which sits in %APPDATA%/FourJs/<Genero Studio version>. Like genero Studio.conf this is an XML file that you can edit manually if you wish to achieve things that haven't made their way into the Studio front-end yet.
if you look inside user.conf, look for a tag ... <Page name="Creatables">
If you look at the XML at this point inside user.conf, you will hopefully see a relation between the XML and what you see on the screen when you select File->New
So to add additional template files, edit user.conf and add additional lines below where there is an existing template being made available, and save the template file alongside the additional template files inGSTDIR\bin\src\studio\tpl
I'll add the proviso, do not edit the user.conf or genero Studio.conf whilst Genero Studio is open. When Genero Studio is closed, it will overwrite your change to these files.
And a disclaimer that this may change in future versions so don't invest too much time creating templates and making these changes and expect them to work in future releases forever. I expect one day there will be a File->Save As Template that will do this automatically for you.
