Is it possible to configure git options for the "Rebase children of <SHA> interactively" command?

[Adrian Paul]

When launching an interactive rebase from Sourcetree, is it possible to configure the git-rebase command and/or customise the options passed to it?

E.g. Here is the Git rebase command that appears to be launched by the "Rebase children of <SHA> interactively" menu item...

git -c diff.mnemonicprefix=false -c core.quotepath=false --no-optional-locks -c sequence.editor='C:\Users\<USERNAME>\AppData\Local\SourceTree\app-3.3.9\tools\stree_gri' -c core.editor='C:\Users\<USERNAME>\AppData\Local\SourceTree\app-3.3.9\tools\stree_gri' rebase -i --autosquash <SHA>

Alternatively, is it possible to create a Custom Action for interactive rebasing that might achieve a similar result but still use "stree_gri.exe"?
