Possible to have custom titles in a Blazorise DataGrid when Grouping is used

[well0549]

The Collapse/expamd buttons have a name besides them. Is it possible to show the number of items in the group as well ?
I cannot seem to figure this out...

i Have:
+Domain1
+Application1
+WorkFlow1
+WorkFlow2
+Application2
+WorkFlow1
+WorkFlow2

I would like:

+Domain1 (31)
+Application1 (20)
+WorkFlow1 (10)
+WorkFlow2 (10)
+Application2 (11)
+WorkFlow1 (5)
+WorkFlow2 (6)

So to have te count of th egrouped items in the unexpanded row.

Is this possible ?
