Timeline Data Source - Feed

Hi all, 

In the latest updates to Creatio, you can set a datasource for the timeline component, other than the record page. 



However, if you do this, the feed component is still set to the record, which means if someone posts on this, it does not appear on the timeline. I'm not sure if this has been overlooked at development. 



I'm hoping it's possible to do this in the code but have come stuck. 



I have changed the entitySchemaName to "UsrBookings" which has correctly changed the schema. However, I can't seem to change the column which needs to be PDS.UsrBooking 

			{
				"operation": "insert",
				"name": "FeedComposer_aweotp0",
				"values": {
					"type": "crt.FeedComposer",
					"classes": [
						"view-element"
					],
					"sortedByColumn": "CreatedOn",
					"data": {
						"uId": "fad7ff3c-73da-a7aa-b7be-48fa49cd0d0d",
						"schemaType": "Feed",
						"sortedByColumn": "CreatedOn",
						"typeName": "crt.FeedComposer",
						"caption": "Feed"
					},
					"primaryColumnValue": "$Id",
					"cardState": "$CardState",
					"feedType": "Record",
					"dataSourceName": "PDS",
					"entitySchemaName": "UsrBookings"
				},
				"parentName": "MessageComposerSelector_uxr8sil",
				"propertyName": "items",
				"index": 1
			},

Any help greatly appreciated!
