With more people thinking of and trialing working 4 days a week which is what I currently do, there is no functionality in Hubspot to change which are the specific working days you want your cadence to follow.
I think this would be a good feature to include and I know other systems have this facility. As I don’t work Mondays the cadence means I have Monday’s and Tuesday’s tasks all to do on a Tuesday as they are overdue from the Monday. Not ideal.
