(SOLVED) Is there a way to mark seams by selecting faces?

Was wondering if theres a way to mark seams like this. Im unwrapping a mesh for UV editing. Basically what I want to do is select the faces instead of the seams, then mark the seams. But when I do that it marks all the seams of the faces because their selected. But is there a way to do it so it only marks the outside edges of all the faces in the group? This way I wont have to unmark all the seams on the inside.

Select the faces, Ctrl+E / Select boundary Loop, Ctrl+E / Mark Seam
