UV-Mapping question

Hi, my friends.
I have a problem to texture the object that you can see in the attachment.
The mushroom is unwrapped. I want to use another texture layer to blend the textures between the top of the mushroom and the trunk.
My problem: If I choose "Cylinder from View" for the selected faces (there should the alpha texture get placed) it also changes the unwrapped faces of the first texture to "Cylinder from View". Unwrapped UV-Map gets lost. How can I turn it off?
Anyone can help please? Thank you.
