Resetting individual Document ID

Question

Hi,
I'm looking for a way to reset the document ID on an individual item in a library. Is this even possible? I don't want to do the default option of resetting all (the ticket box in the Document ID settings). The reason why I need to do this is we moved a
document from another library and it kept its old Document ID. 
In testing when using the tick box and resetting it, it fixed the issue. But we have hundreds in the new library and we only want to target the incorrect one. 
Any help would be amazing.
If this is helpful please mark it so. Also if this solved your problem mark as answer.

Hi,
According to your description, my understanding is that you want to reset the document ID for specific library item.
We can  update the document ID using Client Object Model like below:
ClientContext clientContext = new ClientContext("http://sp/sites/mysite");
Microsoft.SharePoint.Client.List spList = clientContext.Web.Lists.GetByTitle("Shared Documents");
clientContext.Load(spList);
clientContext.ExecuteQuery();
if (spList != null && spList.ItemCount > 0)
Microsoft.SharePoint.Client.CamlQuery camlQuery = new CamlQuery();
camlQuery.ViewXml =
@"<View>
<ViewFields><FieldRef Name='_dlc_DocIdUrl' /><FieldRef Name='Title' /><FieldRef Name='ID' /></ViewFields>
</View>";
ListItemCollection listItems = spList.GetItems(camlQuery);
clientContext.Load(listItems);
clientContext.ExecuteQuery();
ListItem item = listItems.GetById(27);
item["_dlc_DocIdUrl"] = "http://xxxx";
item["_dlc_DocId"] = "testxxxx";
item.Update();
clientContext.ExecuteQuery();
Thanks
