Add a Canvas on ListGrid Cells

Hi,

We are preparing our custom component that behaves same like Calendar. We have used ListGrid as a base and now we are trying to add canvas that will represent CalendarEvents. We have problem in placement of Canvas on group of cells. lets say we have a Canvas that needs to be placed for Cells of Time 4:00pm to 6:00pm (in this case 4 listgridcells) So we want to put a Canvas on the ListGrid that will cover time rows from 4:00pm to 6:00pm

Any thoughts on how can we achieve this ? I tried using createRecordComponent() but this places the Canvas in single cell only

Any help will be appreciated
