ie. provision to select/deselect the templates from the list of included templates.

I'm confused. Are you saying you think you should be able to not include templates while importing?

Presently all the included templates are being imported. I like to import only some of the included templates.

While importing, if we get a list of templates (that are going to be imported) with checkboxes, we can unselect the undesired templates from the list.

Thanks for clarifying this.

The easiest way to do this now is to edit the xml dump using a text editor or (harder, but faster) XSLT.
