Partial summation formula for two indexes?

We know that partial summation states that given two sequences $(alpha_n), (beta_n)$, we can write
$$sum_{n=1}^palpha_nbeta_n=beta_nA_p+sum_{n=1}^{p-1}(beta_n-beta_{n+1})A_n$$
where $A_p=sum_{n=1}^{p}alpha_n$.
Is there a version of this formula for sequences $(alpha_n^m)$ with two indexes?

Do you sum over $m$ as well?

Yes, I'm thinking about $sum_{n,m}alpha_n^mbeta_n^m$
