Project Templates with Assignee

We have created templates (including up to 20 tasks) for campaigns that require the same process each project. Certain team members are always assigned to certain tasks (i.e. paid advertising). Because team members are assigned within the template, they have a task "to do." If they mark it complete, the task (within the template) will be marked as complete even when duplicated in new projects. Is there a workaround to have team members assigned to the template without those assigned tasks (within the template) showing up in their workload?
