How to add custom report link or doctype link in Workspace?

I’m using v.15. Here, I cannot create new workspace or duplicate workspace. Now I want to add a custom report link or doctype link in the workspace from my custom app. How can I do this?

U know you can create own custom html block and add that in workspace or if u need doctype link means by clicking that need show the list views then you can add the shortcut in that workspace

Add your shortcut in your workspace and add it your custom report.

@NCP Its showing changes json in the defualt application like ERPNext or hrms. Not in my custom app
