Support coping to tracks

First of all, I have choosen the programm because it is the best for my needs - as I think for others too - cataloging CD's.
Now my idea: as I'am a Classic-Fan, I have always the same "stupid" copying to do, to use some features in my set up.
I porpose a function to copy the composer and the artist on track level to dedicated other tracks (like copy from actual track to track starting with nr.a to nr.B). Nice would be this feature for the Recording data (Valid for all sentences of a Symphony)
Another good feature would be to insert the Composer on General level, so that it is valid and default for all tracks
The same function would be helpfull for the Artist field on track level.
(I can explain my proposal closer in relation to setup I have choosen)
