Facing Error while using "TeamWork" Functionality in Add Activity Type

Content

What exactly I am trying to do is I am creating an activity by enabling Teamwork features but the problem is that by enabling this I am not able to create the activity from the OFSC because it's not allowed me to pick up that activity which was enabled by the Teamwork features. And the reason behind this is while I am checked for the Teamwork features the Allow Creation In Buckets features will unchecked automatically( this is OFSC default configuration). So is their any way to create the activity through OFSC(related to the above mention context).

I would appreciate any answer.
