Texture sizes and UDK Packages

Everything has been going smoothly besides one thing. UDK keeps reminding me every time I save that the  package is over 300mb and that I should split it up. I was wondering why it was even saying this at all, but then I realized that most of my textures that I imported were 2048x2048. I forgot to resize them before bringing them in and it is eating up most of the recommended 300mb limit per package. So, I'll be spending some time resizing the textures to 1024x1024 in photoshop and then creating new packages with both the models and the textures that go together and then using the replace option to quickly swap out what I need to in the level. It shouldn't take long but at this point I can't be wasting too much time.
