I am not sure if I understood your question correctly. Do you want to 
switch the template of a file depending on its parent folder, rather 
than tying the template directly to an individual page?

As far as I know you can set the template property on a folder and not 
on the files in that folder. In that case, the folder-setting should 
carry over to your files.

This should also work with several folder levels in between.
However, if a file has an explicit template or template-elements 
setting, then any setting for your parent folders will not have an 
effect. A folder cannot override the settings for individual resources.

Again, I have not tried setting templates through folder properties - I 
think that it works but I could be wrong. Maybe someone else has 
actually done that?

Also, what you can definitely do is to create some kind of meta 
template, where all resources have the same JSP template assigned to 
them, but the code of that JSP decides, which actual template gets 
included an thus used. (And of course, for that decision, you yourself 
could check parent folder properties and include the desired template 
into your meta template, as needed). This will definitely work, since 
you have complete freedom of what you do in your JSPs.
