Hi,
We have created shared parameters for InstanceRevisions and for TypeRevisons.
We also have Tags that diplay an arrow and a date or revisionnumber.
Revisionnumbers come from an Excelsheet with revisionsnumbers, desciptions and approval dates.
Only approved revisions will be in the Revitmodel.
Since those parameters are Shared parameters, they can be scheduled and edited by Dynamo.
You can use parameter mapping to fill the schedule.
