Is it possible to avoid large writing to disk?

Hello,

When one runs event generation with MadGraph, quite a large number of files are written to disk (for example to the SubProcesses folder). However, often one only wants to use some of the final outputs. I am wondering whether there is a way to run Madgraph with minimal writing to disk, storing much of the intermediate information in memory, and only outputting what is necessary.

Is there such a way to run MadGraph?

Thank You
Chris
