Create meta graph of subset of nodes

After checking all the meta.graph and db.schema functions, I could not find one for the following case: i would like to be able to get the meta graph based on a selection of nodes.

For example, meta.SubGraph is the exact opposite , given that the number of Labels is quite high and there is only 1 relationship type - thus, none of the input parameters to filter the original (full) graph are helpful for my case

Any idea would be much appreciated
