Dynaminc display

Hello
We have a single dataset that lists all the scheduled meetings in different rooms.

We would like to display the upcoming meetings for each room (with automatic scrolling on the screen, room by room, along with the associated meetings).

We used a layout with a DataSet string element to display the room.
However, we couldn’t figure out how to display only the meetings for that specific room.
Is it possible, in the dataset filters, to reference the value of the dataset element that displays the room?
