Can accounting be reversed for bank statement accounting on the Reverse Accounting Request page?

We are on Image 34 and I need to reverse some bank statement accounting. If I delete the journals in valid status or unpost the journals that posted it looks like it creates the journals again. But when I try to use the reverse accounting request page, it does not find any BSP accounting ids even though they are viewable on the Accounting Events page (BSP Accounting Events tab) under Treasury Accounting. How can I get rid of the BSP accounting?
