Would it be possible to maybe purchase any remaining custom slots as add-ons later on, or something like that? My sister lost two of her dogs this past year, both via tragic circumstances. I backed for a custom slot to have one of the dogs made, but I'd like a way to do both of them. But on top of that, I'm pretty financially tight after backing the first custom slot, so if there is a way to get a second one, could it possibly be purchased as an add-on later when the surveys go out? Sorry, I know that's probably a lot to ask, but I figured it wouldn't hurt to throw it out there
