I am developing my own CRM+PSA system. (Professional Service Automation or Project Service in Dynamics 'speak') I am using Common Data Service Model Driven App. I see that in Dynamics Project Service there is a grid-like weekly timesheet functionality (see picture). Are there any UI components available to me in MDA to replicate this kind of view? I have been using editable grids, but this seems to be a different UI element altogether.

Also, another quick question, is there any significance to the Calendar Icon to the left of Time Entries. I notice that if I add various entities from the CDS Core set i get different 'icons'. If i add my own custom entities I get a jigsaw type icon.
what is the significance of the calendar icon and are there any existing entities that come with the sort of calendar/grid UI i would like to emulate?
