If we are married and combine incomes as SE, can misc expenses go where they will do the most good?

We are both over 65. We are both writers and work in p.r. and theater. My spouse is showing a loss this year; I am showing a profit. Since we are filing with combined incomes can I use misc. expenses that aren’t benefiting us on his Q&A, but would benefit our combined income if they show on mine? Our travel and meals, for example, are combined anyway as we both work in the same field and meet the same producers, clients.
