Id attribute for back button in standard reports

Hi all, lately have been working on html reports. I have created custom home page as a standard html report in which I have categorized the reports as per user needs. When user selects any report from this page corresponding html report will be generated. After generation of the report when user clicks on BACK button it will take us to dhis default reports page. To fix that in my html report I looked for second button (which is back) and overwrote onclick event. This is working fine but if we add more buttons or if button order changes then it won’t work.

The easy and doable solution could be having id for button tag like the way we have for print button.

If there is any other option please let me know. Thanks
