Limit "Assigned to"

Hi –

First: AWESOME PLUGIN!

Second: I would like to limit the people that a task can be assigned to, or maybe who can do the assigning.

Is there any way to restrict this privilege through user roles so that only an admin can make an assignment?

Is there any way to setup a default so that a task is always assigned to a default set of users, for instance I can assign it to myself or to the admin, but no one else?

Thanks,

– J
