Adding data to one dataset affects Other datasets

I have read through the suggestions on page and could not see direct
similarities between mine and other suggestions, but feel free to
delete/move/merge this one if I missed one!

Here goes...

I eat food
I eat various kinds of ice cream

I'd like to plot over time what becomes my favourite ice cream by numbers
(Although it's probably going to come out with Ben n' Jerries!),
But I'd also like to add the fact that when I add one to the "Ben n'
Jerries" list, it adds a point for ice cream as wall, I'm eating ice cream!
Sort of like subsets of data if you know what I mean (This is sounding more
and more like a Venn diagram...I thought I'd left them behind at school!)

So for example:

Add 1 for Baked Alaska (Ben n' Js flavour)
That adds 1 for Ben n' Jerries (Ice cream brands I eat)
That also adds 1 for Ice Cream (Food i'm consuming)

I didn't know if that was a feature or not (Or can it be done now?) or
whether it would be possible, but I thought it would be really cool
