Can I create and share a special purpose calendar?

Not wanting to integrate with my calendar, rather create a calendar sheet and share that with other users for collaboration. I imagine a monthly calendar lay-out in which the users can insert activities due on that day. No need for specific hours, alerts, pop-ups or generating invites - really very simple! However can´t find this feature. Does this need a plug in or add on? I know Google docs has this, but since I have other sheets on Smartheet and one app, would prefer having a one-stop shop. Anyone out there that has already figured this one out?
