Notation: Apply summation to elements of a vector

Question

Suppose I have vector $\boldsymbol{x}=(x_{1i}, x_{2i})$ and I would like to sum each vector element over $i=1,\dotsb,n$, so my new vector should look like this: ($\sum_{i=1}^n x_{1i}, \sum_{i=1}^n x_{2i}$). Since my actual vector $\boldsymbol{x}$ contains more than two elements, I was wondering whether there is a short and clear notation for taking the sum of each element without taking the sum of elements.
