I've looked at doing a dword fetch from the first two words of the 0/1 userdata, It's not optimal for vulkan unfortunately, since the idea I had was per command buffer I just allocate one scratch buffer of the size required at the end, and patch it in at the start of the command buffer. However in the first slot I was going to use the push constants/dynamic buffer to store the value, however it looks like I need to keep a list of everyone of these buffers I emit, and backpatch them all. It might not be too insane, just a slight bump in the keeping it simple.
