Easiest way: try it!
My understanding is that data feeds override all settings (for which the boxes are checked) each time they’re pulled.
If you want to keep @Cybnate’s data feed registered, but vote for mine as well, uncheck motions from @Cybnate’s data feed and enter both motions manually.
That should work.
But please verify it!
As far as I understand frequency voting, you’d be better off with it in such cases (assuming some people vote for @Cybnate and me)
