Adding another upvote to this suggestion!
We are trying to set date-based workflows for expiration notices - the expiration date is based on an “application processed” date property, the latter of which we can set via workflow. However, I have to use Zapier to copy and then increase the value by 1 year and send it back to Hubspot. Would love to do this without a third party.
Right now we can increase property values that are number-based but not date-based. Seems like the functionality of the “delay” option in a workflow based on # of days would have some cross-over to developing this option.
