**Which product are you using?**  
PDF.js Express Plus

**PDF.js Express Version**  
8.1.1

**Detailed description of issue**  
We have situations where we need to load 1-4 pdfs on a single page, however I noticed that it will load duplicates of the same JS files. Is there a way to create instances that will share the same files and not load them all over again?

**Expected behaviour**  
Create multiple pdf instances without loading duplicate js files.

**Does your issue happen with every document, or just one?**  
All

**Code snippet**

```javascript
<div id="document1"></div>
<div id="document2"></div>

```

```javascript
WebViewer({
    path: '/Content/pdfexpress/public',
    licenseKey: 'key',
    initialDoc: `document1.pdf`,
  }, document.getElementById('document1'))

WebViewer({
    path: '/Content/pdfexpress/public',
    licenseKey: 'key',
    initialDoc: `document2.pdf`,
  }, document.getElementById('document2'))

```
