Limit the number of templates a user sees in Structure

I have an area of my site which is managed by a community. They have control panel access to their area and can only create content for their specific area. I’m using the Structure module to simplify page and content management.

I have already set the default template in Structure so it is automatically chosen as the default for their section, however I expect to add additional templates in the future. We already have a large number of templates for other areas of our site and in order to keep the management of content as simple as possible, I’d like to limit the number of templates they see to only those that they I want them to actually use.

Is there a built in method to do this?
