I have a site with a Document Library, and a Task list both of which
I have created. I have a SharePoint Designer workflow set to kick off
whenever a new item is added to the library, and it populates the task
list I have created with a custom form from the workflow assigned to a
list of people also in the workflow. That part works great.

I have another list of names that the proponent can add and delete from
as needed, and I have an alert sent to me with any change to the list so
that I know when to add or take someone away from the workflow. What I
have done now is created another workflow and attached it to this list
of names so that it actually assigns me a task to update the permission
groups and the workflow roster when a name is changed. The benefit over
the alert is that I can assign that workflow to a group (say, admins) so
that more than just me get notified. That part also works well.

The problem is that I would like to have this second workflow populate a
different task list with those tasks. I am unable to see the option, if
it exists, to specify the task list to use. It seems to automatically
populate the task list in use. I haven't experimented much with this yet
to be honest, and I have the one task list manageable simply by adding
another logic statement to each of the views I had previously created.
It just seems like it would be easier from a maintenance standpoint if
the tasks were separated into different lists.
