A "mark all flights" on codesharing

[Marc Joy]

Hello guys...
Actually Vorona Aviation is going trough a major restructure on flynet, separating it in divisions.
But I think I'm not the only one to undergo codesharing..

Would it be possible to have the "checkbox" (like in the flightplan) to be able to click fewer times when codesharing ?
Same for accepting all codesharing proposal for instance ?

Thanks for your thoughts
Marc
