Grid: Loading rows indicator like Table


We’ve migrated one of our views from Table to Grid, using Lazy Query Container Add-on to fetch data from backend.
One thing we are missing is the loading rows indicator Table brings along.
We are faced with the requirement to give the user feedback in case additional rows are loaded. Haven’t the chance to load all cause there may be quite a lot.

Is there an easy way to realize such an indicator in Grid?
Is there a possibility at all?

Thanks in advance!
