Addons for non-kickstarter backers

I read on the kickstarter that at the end of the pre-order period there might be some upgrades available (like the enclosure for the Snapmaker 2.0).

If I order the snapmaker 2.0 now through the website, will I also have the option to add these to my order later? I can’t seem to find anything about that in the FAQ (but might have missed it of course).
