[Observium] mini-/micrographs stacked / aggregated?

Greetings

Is there a way we can create "aggregated" (or "stacked") mini-/micrographs for the frontpage? using this syntax

$config['frontpage']['minigraphs']['ids'] = "19418,port_bits,Dist76-01.AMS4;19496,port_bits,NAME"; or this: $config['frontpage']['micrographs']['RING']['ids'] = "19414,port_bits,NAME;19492,port_bits,NAME2;19439,port_bits,NAME3";

results in several graphs next to each other.

what we are after is in "mini" or "micro" what we can do it using "custom" traffic graphs - but they are too big for what we are trying to do...

$config['frontpage']['custom_traffic']['ids'] = "19418,19496"; <-- this actually stacks the data into one graph

thanks for any pointers!
