This is probably a stupid question but I thought I'd run it by you experts anyway!
Is there any reason why you couldn't fill multiple molds at one 'sitting'? I mean, assuming you're willing to use the same chocolate could you fill - i.e to create the initial outer shell - scores of different molds in one go? Then you could just reach for them as and when you need them, which presumably could save some time and effort further down the line. Surely better to blitz the issue in one big go than do the odd few molds here and there? You could store the molds as you would empty ones, perhaps with some parchment paper in between. There would be no shelf life questions as it's only chocolate (so no water activity issues) and if stored correctly I can't see why you couldn't do it and then not have to mold (beyond backing them when needed) for months.
