Help Adding Date Picker to Personalised Product Page

[SteveWinch5DS]

Hi All
Here's one for you... 
We currently use Zepto Product Personalizer on some of our products, and for our needs it works perfectly fine.

To throw a spanner in the works, for ONE design only, I want / need to add a Date Picker to a product to combine it with the Personalisation. It can sit under the Perso fields, doesn't have to integrate with them at all.

Firstly, I've created an alternative Product template, named 'product-pers-alt.liquid', just for this design (and any others we decide upon going forward) BUT when it comes to creating that Product, I'm unable to change the product template to the alternate one. Where / How would I do this?
I've previously created alternate collection templates in the same way, and been able to switch between them at will. But not able to for Product creation? 

Secondly, where in the Product Template code would I add the Date Picker code  {% render 'wedding-date' %}  for which I have already created the Snippet?! 

As always, all help / advice gratefully appreciated! 
Cheers
Steve

Using MINIMAL theme by the way, if that makes any difference? 
Thanks
