Filtering Schedules

Schedule filtering, Whats the Node.
heres a link where The filtering of the schedule is still done manually. anyone know of a way to access the filtering
of schedules. Seems we are able to sort, modify appearance, set columns and cells and not Filter Scheduels yet.

Reading from other post Assembly creation hits a stumbling block when filtering the schedules with dynamo. Although there appears to be some API access.
