As a workaround you have suggested to manually calculate the split.
In my example I have got one T3 with filled boxes 49,50,51,21,37 and 58,52,53 and
another T3 with filled boxes 49,50,51,21, 34,37 and 25,58,52,59,53
Which information in which exactly boxes do you split 50/50 between the spouses? Do you have to split information in all the boxes?
