Add another "Run" button

Is it possible to add a button close to the "Run" button of a build configuration?

Here (build config overview):


and also here (project overview):


I'm looking at the list of PlaceIds and I can't see one that would let me put a button here. Am I missing something?

(The button should open a Run-like dialog, where the user can select two finished builds from a build configuration, and run culprit-finding between them. Example: build A finished green on Monday, build B finished red on Tuesday. Build B contained 5 changes. The culprit-finding will queue the intermediate 4 builds between A and B, to identify who broke the build.)

Perhaps BUILD_CONF_TAB is a suitable alternative. Rather than having a button that opens a dialog, I can create a tab on the build configuration. But the button would be nicer I think.

Any advice appreciated.

Thanks,
Sam
