In AT v3 it is possible to assign multiple Categories to a Song by deleting the Song Number and assigning a new Category - as many times as required it seems. AT v4 only seems to have a single Alt Cat field and no way of deleting the Song Number to allow the same functionality as v3.  I am therefore limited to only 2 Categories per Song, which sometimes is just not enough.  Any ideas/solutions gratefully received, many thanks.
