Adding metadata to cells, Possible?

[LinArcX]

Hello and thanks a lot for creating this software.

I'm going to use sc-im for my personal accounting stuff, like managing income/expenses and calculating the remaining money for every month, these sorts of things.

And I think it's an excellent idea to add metadata to each cell.

For instance, I bought some foods on September 22th, so adding it's number in a specified cell is easy. But also I wanted to know why I spend this money on that day.

So the ability to add metadata that is part of each cell but it won't be part of calculations is a helpful option.
