naming template

[marchermitte]

Hello
There's something that bothers me, when exporting an animation, the default template name doesn't work as It is, the sub frame adds a_1 at the end of the sequence making It unusable without renaming every image.
Now that I know that, I remove of course the _%s from the template but if you ever forget, you're back to renaming the whole sequence.

Shouldn't a default template work as It is for standard outputs?
