Apply discount codes to specific blocks#215

Would it be at all possible to add an option to specify blocks that a discount code is valid for? Even something more general, such as ‘blocks not currently in progress’ would be a useful filter for us, which would enable us to offer discount codes for future dates without needing to check manually whether those codes are being used for current blocks.

This is a great idea. I like the “blocks not currently in progress” suggestion.
