We want to use the sequential options type, because otherwise the first option is selected and it that one happens to be out of stock, it may make the customer think the entire product is out of stock.
We also want to use a global option for our different sizes for various reasons.
However this means all the size variants in the global option appear is if they might be available. Example here: http://www.katesclothing.uk/restyle-pentagram-maxi-dress.html
This is not ideal because it makes it look like all these sizes might at some point be available, when in many cases they will not.
Is there a way to have sequential, global options but have the options that will never be available not be listed on the product?
We have tried both adding them as exceptions and deleting the non-existent options after rebuilding.
