[Flow] How to use multiple Persistence Backends?

[Christian Loock]

Hi,

I wonder if anybody allready managed to use multiple persistence 
backends at the same time or at least managed to configure persistence 
on package level. Currently i need to define some settings in the 
Objects.yaml on Project level, not on package level which basically 
means that I can only use one Persistence Manager in my Application.

Is there any known solution or workarround that you are aware off? If 
so, please let me know.
