Hi All,

I would like to run a separate over individual filters. Specifically imagine I have two matrices and I want to convolve each of them with its own filter. And I wonder if it possible to write it as a single convolution.

MWE should be as follows

```
x,y = randn(3,3,1,1),randn(3,3,1,1)
Cx, Cy = Conv((2,2), 1 => 1), Conv((2,2), 1 => 1)
xy = cat(x, y, dims = 3)
C = ???
C(xy) = cat(Cx(x), Cy(y), dims = 3)
```

where `C = ???`

stands for an operator I do not know how to write.

Thanks for an help in advance.

Tomas
