Hi @orcalator,
So far as I know there is no QuickSubmit plugin for OMP, but you may be interested in the plugin mentioned here (by a third-party developer): Quicksubmit plugin for OMP - #7 by ajnyga
However, it has not been tested against 3.3, so I cannot guarantee it work. As is the case when using plugins outside of the plugin gallery, I would exercise using caution when installing plugins outside of the plugin gallery (https://docs.pkp.sfu.ca/plugin-inventory/en/#find-a-plugin-compatible-with-your-software-version)
