filler

hi all - quick question … in order to keep frames in sync with other frames as many a time i have had to adjust their locations in relation to each other, especially when i bring something down from the global library, i throw in blank cells (sort of like filler cells) … i know i can just make a pencil mark somewhere outside the camera area in order to avoid the error i get each time i load the project that tells me such and such cell can not be found (it’s the blank ones), but i think it’s a messy way of doing things… I just wanted to see if there is something out there that anyone is using to bypass this error besides just making a mark somewhere outside the camera area … thanks, dan
