How to do multiple gradients on one layer?

[Airick1994]

I'm making a picture that looks like this currently:

What I did, was do a Linear (Reflected) Gradient from top to bottom, then, on a layer above that one, do the same gradient, but sideways, then make the layer opacity 100. Now, I want to have three of these gradients on this line image, but you can only do one gradient per layer. If I go up a layer, I ahve to make that semi transparent as well, but that just makes the layer two below really hard to see, and ruins the image. Is there any ways I can get three gradients on one layer?

I'm going to try to copy and paste the gradient, but there must be a better way than that. Thanks in advance!

Hope this helps.

So, just select the part I want gradiented and deselect? And it'll let me do it multiple times per layer?

I will try that soon, but I achieved what I needed to via copy and paste:

Thank you very much, because I will definetly use that technique.
