Can I save and edited template (from "Edit Template Drop") to a Template Library (itl)?

Hi.

If I open the "Edit Template Drop" window and I edit the current template i.e; I remove the central component to have a "V" median can i save that current template to a itl file? Is there any way to change the name of that current template before saving it?

In the "Edit Template Drop" the menu bar File-Save, it saves the current itl file but I don´t understand what it does.

Thanks in advance.
