Feature suggestion: Support copy tracking during timing.

[993782githbcom]

You can now copy records that are not currently being tracked, but you cannot copy records that are currently being tracked.

Request for support

Hello! It should be possible to add, although with some limitations. Two timers of the same activity is not possible, so clicking on Copy action for currently running timer will probably show an activity selection dialog, to copy data to new activity timer. Selecting same activity that is already running will probably not create another timer but a record.
