Workflow / CuePoints

Hi..

just 2 short questions:

where is the information (cuepoints, playlists, waveforms..) stored when exporting to SD? i could not see any additional files on the card?

if i export tracks to SD/USB .. then, during the gig, i play around with cuepoints, loops. hot cues and so on.. how is this information getting back to the rb software? next time i plug in the card it just asks me if i want to "save history as playlist".. nothing about like "would you like to update your track info" or so..

thanks
