Is it possible to restore opacity in a semi transparent PNG?

Through the channels window, I can paint on the R, G and B channels individually. That's great, but where's the Alpha channel? Photoshop only allows me to create a new opacity layer which simply subtracts from the PNG's native opacity - it can't add to it. What I need is to INCREASE opacity. In other words: I have parts of this PNG which are semi transparent, and I need them to become opaque. How can I do that?

Yeah, it seems this is the only way photoshop can do what I need. I can duplicate the layer a bunch of times, collapse it down and apply a mask to it so I can paint it in slowly and precisely. This is a very inelegant and ham-handed solution to the problem and I'm very disappointed Photoshop doesn't have a better solution. All pixels in an image have R,G,B and Alpha channels stored. The fact that you cannot access the Alpha channel is a GIANT GLARING inadequacy in the design of the software. But thank you for your help, everyone.

Would it not just be easier

Would it not just be easier to duplicate the layer a few times, until it is a solid colour, then merge the layers?
