Can MF LTCG be shared with spouse when purchased through joint funding but held in single name?

Here is the scenario - 
1. Both husband and wife are working professionals with separate earnings statements and salary accounts
2. MF portfolio maintained in single name, i.e. husband
3. MF purchases funded through salary accounts of both husband and wife
4. Sale of MF units resulting in long and short term capital gain

Question: Can these gains be split between husband and wife since the purchases were funded jointly (though the portfolio was held in single name)?
