Yes, this is what I would do if I needed multiple leaders because then I would still have all that the Label Tool offers.
You can also consider grouping the additional Leader Lines with the Label so they can be moved together.
(I am assuming you are coming from Revit because you call those Labels Tags, which is Revit terminology.) So grouping in ArchiCAD simply means that when elements are grouped, they can be all selected by selecting any element within the group (providing the Suspend Groups toggle is not ON), then moved together.
But they don't have the kind of functionality like in Revit, where changing an element of a Group will modify all other instances of that Group.
