iCal to Smartsheet


Hi Community,

I am looking for a solution to export an iCal into a Smartsheet. Our company uses a software to track vacation time and project assignments and can export into a web calendar. Is there a way to link this information back into a smartsheet to show everyone's OOO dates in a Gantt chart?

I've only found an outside integrator such as Zapier as the solution. Is there any internal way to smartsheet to do this?
