Need a command to copy all errors/warnings in the Problems panel

Currently I have to **switch** to the Problems panel, **click** on an Error, **press** `Ctrl+A` **3 times**, then press `Ctrl+C` to copy all errors and warnings.

I need a command that can do this automatically - something similiar to the `workbench.debug.action.copyAll` command for the Debug Console panel.

Thanks!

Start by locating the Problems panel command handling and the existing workbench.debug.action.copyAll command for comparison. Add a command that copies all errors and warnings from the Problems panel, then verify that it works without the repeated selection and copy steps described in the issue.
