Keep the original resolution of the images when making a compound clip?

So I have a bunch of high resolution images (5000x5000), that I have put into a compound clip to make my work easier (bunch of zooming, position changing etc.). However since my main timeline's resolution is 2560*1440p, the compound clip created here is goung to have this resolution. This means if I zoom into this CC in the transform settings, the image going to get pixelated.

Of course if I zoom in the images themselves without creating a CC out of them it is okay, but I want to keep zooming in-out and and changing positions while the different images are swapping.
