Can you add related cases to Accounts timeline dashlet?

Hello,

I've been reading about the Timeline Dashlet (https://support.sugarcrm.com/documentation/sugar_versions/13.0/ent/application_guide/user_interface/dashboards_dashlets/sugar_dashlets/#Timeline_Dashlet).

The Timeline Dashlet only allows you to see related records for Account Updates, Calls, Meetings, Tasks, Notes and Emails. It doesn't allow you to view Case records in the timeline.

Does anyone know if there are settings that can be changed in Admin to facilitate this or if it would require custom dev?

Thanks very much,

Sage
