Open existing SmartGit instance from command line

We have some useful command-line arguments.

But smartgit.sh always creates new windows.

Can a new command-line parameter be added, to apply all parameters like --log and --open to an already opened SmartGit instance, if any?

If there are several SmartGits opened, modify any of them.

If there is no SmartGits opened, ignore the new parameter, open new SmartGit.
By the way, it would be great if --anchor-commit argument worked with --open flag too (not --log only), just focusing the commit specified.
