In website mockups, I design the front page, then duplicate layers constantly for other pages design. Things like the header and footer stay basically the same, so they are copied. Their exact location or dimensions may need to change, though.
Is there a way have an "asset" folder where I'm re-using an image that's already loaded in the PSD, and only modifying dimensions/coordinates? (I'd like to re-use the same layer data for responsive, just shrink it down in size - so if I change the color of the header for example, the smaller responsive header would change as well)
The goal is to get away from multiple PSDs for each page, and just have one PSD for a web project. However, the file is too large right now, but most of the size comes from tons of duplication.
