Reaching out with a possible solution here - our app LinePilot
LinePilot doesn’t create quote templates but it does use templates of line items/products to add to your deals. That way, when you create the quote, the line items are right there. You can have multiple templates of products for different types of deal AND you can customise the line items based on deal properties.
Hope that’s helpful!
