Set Gadget Title if empty


I want to set own title if it is not set by user via rename menu (not applicable for system dashboards).

We have AP.jira.setDashboardItemTitle() and jira.DashboardItem.onDashboardItemEdit(), see also
but no getDashboardItemTitle() or jira.DashboardItem.onDashboardItemRename()

Rename does PUT /rest/dashboards/1.0/10000/gadget/11203/title, but GET same url returns 403.

Is it possible to get user rename item event or somehow get title?

Thank you.
