Caching templates if they exists.

[Sama34]

Well, I asked for this some days ago in the official support community, and nobody answered.

Somebody can help me in this?

I want to cache templates only if they exists, as there may be a lot of them.

Thinking about it right now, may be reading the groups cache at global start and caching a template by each group is the solution.

Nonetheless, hope somebody push me a little in this one.
