Using Graphics Select Tool via Interapplication Communication

Interapplication Communication is extremely limited compared to the plug-in API and often things are impossible that way.

Not possible.

(If it helps to have context, I want to make a program that will copy some tables from PDFs to Excel spreadsheets, and selecting a table via the graphics select tool, copying it, and pasting it into Excel is the only way I've found to do this that doesn't mess up the tables in ways that get rid of information that needs to be preserved, so I figured that I'd make the program select the tables then copy them via , but I haven't been able to find anything for graphics selection in the interapplication communication section of the API reference - it lists AVDocs as having a SetTextSelection function, but nothing simmilar for graphics selection.)
