Feature request: adding another dimension

[Bambuspony]

Another wish: we want to use the fair allocation also another dimension, here it is that the "choices" are only available in special time slots, mainly weeks or 2 weeks. For me it will be fine to have a matrix "choices" + another dimension where I can name the tableheader (weeks) and set yes or no (red cross and green check). Ok the choicepicking needs also some approvement then for the different modes.
Is this realistic or far away?

BTW: there is an ID in the export - what ID is this? Is it important to have in export? May I change it or better: where can I change it to our internal ID?
