Allow user to rename Layout and Maps when importing a layout file (.pagx). Often I have multiple maps within a single layout, and both the Layout and Maps within are appended with a number after the name of the layout file (i.e. Layout Wildlife1, Main Map Wildlife1, Inset Map Wildlife1, etc.). I have to rename these every time I import a layout file, which is time-consuming. I would like the option to rename these items when importing the layout file.
