If you want to do what you described in the original post it would be worthwhile investing a little time in RB. If you open your song with RB you'll immediately see that with RB you can see all the tracks together and 'all tracks really are equal'. But if you are happy with BIAB and just this one instance is a problem you can do without, stick to BIAB. But I promiose getting to know RB pays dividends.
