I realize this may have been asked before but is there a way to make change's to bundles without having to re-publish them as a new version ?

The reason I ask is because we have some very big bundles already installed on some end user PC's, and we need to make change's to the bundle in ZCM and dont want the bundle to re-install itself if it thinks it is a new version.

(our bundles have a launch action after install, so the same application icon acts as an install "if not already installed" or just launch if it is "already installed")

I know some decently written application MSI's can detect if it is already installed and just launch (if the action is set) but some seem to want to completely re-install themselves if they think the bundle is a new version, and I am trying to avoid a long and drawn out install process again.

Thanks in advance.
