Merging subitem timeline/date column to parent timeline/date column

Hello, This is a request to merge subitem timeline/date column value to parent timeline/date column. In this use case, some projects have only single release (parent item) while some projects have multi releases (subitems).

We want to add the timeline/date to parent item for single line items and for projects with subitems we want to add the timeline/date at the subitem that should merge into the same column as parent timeline/date column. I am not looking to add summary of sub item as that will create another column.

Hi @mamta

The app Rollup Subitems (see monday.com: Apps Marketplace) can do that. It summarizes the subitems timeline into to parent item. Different for the option “Show summary in parent” is that the app write to a normal timeline column in the parent. The same column can be used to enter the timeline when the item does not have subitems.

Hi Bas, is this a third party app? We cannot use any third party apps in our organization. Thank you.

This a an app from the monday marketplace developed by a third party. Your monday experience will be limited without using any apps from the marketplace.
