The 'insert proposed times' meeting function is great but at the moment is limited to a maximum of 1 hour duration. This means that it can't be used to schedule longer sessions for things like workshops or detailed reviews.
Impact: longer meetings are often the kind where being able to suggest specific times rather than allowing the recipient to select any availability from your calendar is a huge benefit. It would give greater control to those setting the meeting and the same fluid HubSpot experience for the recipient as they get using the standard scheduler.
Functionality: allow duration of over 1 hour in the insert proposed times meeting scheduler.
Users: any marketing, sales, or service user needing to schedule time with someone where the meeting is likely to be over an hour.
