Open a template, copy 3 worksheets w ranges and save as workbook

[gimme_this_gimme_that]

Is it possible to open run a sub from an Excell addIn, create 5
worksheets,
open a template, and then copy 3 of the worksheets including ranges and
frozen rows, to the template, and then to save the template as an Excel
Workbook?

I don't need an example, though one might be useful, I just need to
know
if it's possible to do it. Especially the "including ranges" part.

Thanks.
