Combine withdrawals from a funding source

If I have multiple savings goals drawing on a single funding source, each goal makes a separate withdrawal from that funding source each month. This means that I get a number of withdrawals on my external account all at once (one per savings goal).

I'd like to see an option to coalesce all withdrawals from a given funding source into one single, SmartyPig-wide withdrawal. This is especially important for accounts that limit the number of withdrawals allowed - thus limiting the number of independent savings goals possible.
