Multi Select Lookup Fields and challenges with Custum Views & Reports

Currently I am investigating custom fields in ZoHo CRM and Multi Select Lookup Fields (MSLF) in particular.
In the Accounts module we configured several new custom fields including two MSLF, one for products and one for packaging items. For those fields I created two new Modules (Products and Packaging). So far so good, this works great !
Then the challenge: when viewing the Accounts list you can use all (custom) fields to filter and show in the columns EXCEPT the MSLF ! No matter what I do it's not possible to use the MSLF in Custom View. Besides that: when creating a new report, I can only select ONE MSLF instead of the two I created.
Can anyone tell me how to make this happen?
