Calendar feed with filter criteria

Dear Podio Team,

we are using a calendar app that is used to both contain internal 'preparation' meetings as well as public meetings (that the preparation is done for, so its the same team).

Now we need to display a calendar containing only the public events. How can this be done? The only thing I came across that could be used as a filter is 'priority', but adding a field with that name etc. did not lead to the expected result.

Please add the ability to include filter criterias for the iCal calendar export/feed.

Right now for us it just seems to be all or nothing which is not so useful. One should be able to leverge the data we already have and not invent a special workaround for this use case.

Best Regards
