We use imports to update our user list with selective access, but cannot do this when one user can have multiple access, e.g. access to multiple countries in a list, because the line item in the module has to be dimensionned by the list itself and in the list we can only select one item. Alternatively we may run the action once with country A, then change to country B and ruen the import again, but that is time consuming, manual and the module cannot be used for auditing access anymore.
