Write arrays to time series pi points

When I have several similar attributes, I'd like to be able to store them as an array of values on a single pi point with the same timestamp. For example: I'm rolling up values for 10 different teams. I currently need 10 rollup analyses, 10 attributes, and 10 pi points on each element. Each is essentially a duplicate of the rest, doing nearly the same thing, just saving a different value. If the data were saved as a 10x1 array, I could just rollup the group and cut my analyses, etc. by 90%. Specific team values could be extracted from the array where desired.
