["Open In External Application" - Modifying a PDF and saving it back]

To be able to do that, I think, would contradict the very purpose of a forensics APP. Investigators are not supposed to alter evidence in any way. 

[Scripting language to automate processes]

Is there a way to automate processes in Intella using a scripting language (CMD commands or othewise) that allows to run several processes in sequence?. I'm not referring to install the app or to index a group of loaded files, but to automate export when (for example) many files need to be exported from several sources, based on different criteria. 

Thanks
