The WP Timeline Designer PRO plugin gives a facility to override post design.
For that, you have to need to install one theme patch for your theme.

When you install the plugin and create a timeline post layout for your site. If you want to override the timeline layout on your website, follow these steps:
Step 1: Now go to your site root directory using any FTP tool or cPanel.
Step 2: Go to wp-content/themes/Activated_theme
Step 3: Now create that “wp_timeline_templates” folder into the “Activated_theme” theme folder.
Step 4: Now create that “blog” folder into the “wp_timeline_templates” theme folder.
Step 5: Now upload your blog layout file and file path is /wp-content/plugins/wp-timeline-designer-pro/wp_timeline_templates/blog/YOUR_TIMELINE_LAYOUT_FILE( like as story-layout.php file)
