Yes, but new flag for that purpose ('-n' for example => nextboot).

I.e;
    # 'boot0cfg -s 4 -o noupdate -n 3'

Would, set the default/main boot selection to slice 4 and  '-o noupdate'  ensures it remains that way, while '-n 3' would auto press/choose slice 3 in selection menu, as human would.
Well in that case, better to not show menu at all, thus only "blic" into slice 3.
At next boot it is at slice 4 again.
