I don't think this is currently possible. (if this is please explain how this is done).

Having a standard "issues category list" user selectable inherit option, for sub-projects would avoid a lot of re-keying and data errors & break-by reporting issues.

This would be useful where project issues / tasks are used for process (or lifecycle) tracking ...

eg.

Inquiry ... Quoted ... Ordered ... Staged ... Shipped

or

Speccing ... Coding ... Testing ... Deployed & Complete ...

or

RNA given ... Item rx'd ... Repair Assessment ... Quoted ...
PO Rx'd ... In repair ... Returned complete
