Audiostream selection changes for 2. moviefile

hi

i have a english movie splitted in two files on my hdd and two additional audiostreams in german for each moviefile.
i made two bsi to set the 2nd audiostream.
everything works fine, but when selecting 2nd audiostream and bsplayer starts the second part, in does not keep my audioselection, but start the second part with the english stream. so i have to reselect the 2nd audiostream manually.
can i change this?
