Execute Add-in after template?

Is there any way to execute an add-in after a template has completed its function (add folders, fill in meta data, etc).  I have a template that adds a folder for a document that has a generic place holder pdf.  I want to add a solidworks or other templated file based on another piece of data (customer, etc) filled out in the form.  Each of our customers has certain requirements of fonts, dims, etc so I'm trying to get to a point where adding a native drawing file with the customer's settings is possible.  I could use a PDM template for each customer but we have many customers and hopefully that will continue to grow.

Any ideas?
