Is there a way to only reformat files I have checked out, without checking them in?

I'm sorry if this is obvious, but I can't figure out how to do this. . .

I'm using Perforce, and have my project setup with P4.

If I go to VCS | Commit Changes, it pops up a dialog that has a "Before Submit".  On the left side of this, it has a number of cool options: Reformat Code, Optimize Imports, Scan With Checkstyle, etc.

I'm assuming this is only run over the checked out files?

If so, is there a way to run these on all my checked out files without actually checking in?  At my company we have a separate commit process, so I can't simply do a P4 Submit.  I need to call into custom tooling.

    Thanks!
