From what I can see, there is no way to add a Lead to a Target List other than from the List View Screen and bulk selecting…
Is this the most logical way to do this?
For instance suppose you are working in a Lead Record and you want to add them to the Target List from within the Lead Detail View. That doesn’t seem possible…
I would really like the Subpanel in the Leads Detail View. I thought it should be there anyway, since there is a default relationship of Leads:TargetLists, no?
Maybe. I guess most people just use the Lead in one Target list, and somebody though it should be kept simple. But it’s not a big effort to add the subpanel, so try it and see how it goes.
