When creating a review from a URL, is it possible to set the base branch?

[William Heineman]

When creating a review from JIRA, I navigate to a URL:

http://<crucible server>/cru/createReview?addContentMethod=method-track-branch&repositoryName=<repo>&reviewedBranch=<branch>&origin=jiraissue

This creates a review from <branch> relative to "master".

Is it possible to set a query parameter to change the base branch?

IE to create a review from <branch> relative to <base branch> (not master)
