Can two Multiplus provide the same functionality of one Quattro?

I know that "Similar to the MultiPlus, the Quattro is also a combined inverter and charger. Additionally it can accept two AC inputs and automatically connect to the active source."

now if buy 2 MultiPlus, can they be configured to work together and provide the same functionality as 1 Quattro, another words: can I accept two AC inputs and automatically connect to the active source when using 2 MultiPlus at the same time.

the answer to this question is not clear, there are conflicting information about this question, nowhere in the manuals i could find a direct answer. would be nice if someone from Victron could provide a definite answer.

--Added--

I am assuming that 1 Quattro can combine the power of 2 different AC inputs for charging of the 1 battery bank, but i might be wrong in my assumption and 1 Quattro might be only able to automatically switch between 2 different AC inputs.

Should be possible with the "VE.Bus System Configurator" and selecting "2 AC inputs"
(open VE.Bus System Configurator, click on "help" and on "Tutorial" to learn how to use it)

In this configuration, how are the Multi's wired? Specifically what happens on the AC inputs and AC outputs? Do the Multi's combine power for the output?
