Yes, you can utilise wildcard approach (in conjunction with clearing the validation selection (ie delete cell content so it reverts to blank))
Would SUM C1:C1000 where A range = D1 value "plus anything" and B range = E1 value "plus anything" ... so it follows that if D1 is Apple and E1 is Banana it will look for "Apple*" in A and "Banana*" in B ... were D1 and/or E1 blank it would look for any value at all - ie "*" ... if D1 were A it would look for "A*" etc...
Pending the values in your own file it may be that you will need to adapt the above approach by means of embedded IF if wildcard entry not watertight, eg:
If the above do not work for you then as Palmetto has already stated post a sample file that reflects your setup.
