views – Show latest content date from group content type

I’ve a group type vendor with following groups:

Each group is associated with content type notes as shown below:

Notes (Content Type):

N1 (Group: V1)
N2 (Group: V1)
N3 (Group: V2)
N4 (Group: V2)
N5 (Group: V3)

I want to create a view where following data should be displayed:

V1
    Latest content update date
V2
    Latest content update date

But I do not want all the contents update date listed. When I use grid layout I can group the content as per associated group but the output contains all the last updated date for all contents. I want to limit the output only to last 2-3 contents.

Example:

Views -> Grid Layout -> Group by group title -> Number of columns per row -> 2

Output:

V1

N1 last update date     N2 last update date

V2

N3 last update date     N4 last update date

Expected output:

V1

N1 last update date

V2

N3 last update date
