With the extended Merge Info functionality, you can view and update changelists' integration status.
Subversion stores the information on whether a changelist has been integrated into the local working copy or not. Based on this data, DataGrip informs you on the integration status of a specific changelist by displaying one of the following icons next to it:
integrated
not integrated
integration status unknown
common history
To have the integration status displayed, click the Highlight Integrated button 
on the Merge Info pane toolbar.
You can change the integration status of a changelist without actually integrating it into the working copy or reverting the previous integration. This will affect only the administrative data.
To toggle the integration status of a changelist, do one of the following:
To mark a changelist as Integrated, select it and click the Mark As Merged button
on the Merge Info pane toolbar.To mark a changelist as Not integrated, select it and click the Mark As Not Merged button
on the Merge Info pane toolbar.
