adding new tasks to a campaign

adding new tasks to a campaign

Hello,
I have imported my leads into Zoho CRM and set up a campaign. I now want to assign tasks linked to the campaign and my leads but there appears to be no way to do this.
I can only find a way to link my campaign tasks to Contacts or Potentials. When I select Lead on the Add Task screen the Campaigb pick list is disabled. Is this an oversight or a deliberate feature? If so, do you plan to allow it in the future?

Or is there a way that I cannot find?

With best wishes,

VY
