Report Manager: Dynamic Widget Title

We are using Report Manager to send automated reports for some of our dashboards. We have scripts on our widgets that will change some of the titles depending on the code filter selected. The scripts work fine on the dashboard, however, they are not working when we use Report Manager. 

We are leveraging the "+ Apply Custom Filters" option in Report Manager so the reports are specific to a certain topic, date range, etc. The feature filters the reports fine, but the widget titles are not updating.

Can anyone assist with this?
