Yes, it's possible if you use KoBoSync to aggregate your data. KoBoSync will separate multi select questions into discrete columns.
Your survey, if made using KoBoForm, will indicate multi select questions by appending _MULTI_ to the name of the node in the instance.
So, if your question is A01, it will actually be A01_MULTI_. Then, when you run it through KoBoSync, each possible answer will get its own column, like this:
A01_MULTI_1, A01_MULTI_2, A01_MULTI_3, A01_MULTI_4, A01_MULTI_5
If the checkbox is checked, the column will have a 1, or a 0 if not checked.

It would be interesting if the options selected on a MultiSelect Question in ODKCollect been stored in diferent variables. Like : A01 = 1,2,3 for A01 = 1, A02 = 2, A03 = 3. Is that possible???
