No. Not unless you’ve put the custom content on layers that are shared across pages. Duplicating pages is another way to have the same content on multiple pages without having the content on a shared layer.
Normally when you make a template, you should create as many pages as you will commonly use. Also create appropriate layers for the content. Create layers for template specific things like borders, title blocks and page numbers. Put them on layers as needed. Borders and pages numbers on shared layers while title block might be on an unshared layer. Create additional layers for project-specific content you’ll insert or create. So that’s layers for viewports, dimensions, other text, drawing entities (Scaled drawing stuff.)
