collate cash flow series by dates

[team_qq]

I have 3 large series of cash flows, each with its own unique set of correlating dates. I am trying to figure out a way to collate or merge the cash flow series' in order to calculate the return using the XIRR formula. If the cash flow series were small enough, I could stack them, since the XIRR formula doesn’t require cash flows be in order, or cut/paste and data sort. However I am looking for an elegant solution that ideally can collate the three cash flow series with dates into one cash flow series with dates (without requiring manual cutting/pasting/sorting), or some way to apply the XIRR function simultaneously to all three cash flows.

I have attached sample cash flow series in problem form and how I'd like the solution to look.
