How To Avoid Non-published Columns Deletion On Subscriptions' Reset

Hi all!
I have been doing some testing with transactional replication. I have a table (TEST) with the following columns:

[id] [int] IDENTITY(1,1) NOT FOR REPLICATION NOT NULL,
[name] [varchar](50) COLLATE SQL_Latin1_General_CP850_CI_AS NULL,
[stock] [int] NOT NULL CONSTRAINT [DF_Prueba1_stock] DEFAULT ((0)),

I want the table rows to have an independent stock value for each database. So,
I made a transactional publication with updatable subscriptions, to replicate all the table columns, except the stock column.

The problem is when I reset subscriptions: the table is deleted an created again on the subscriber, so all the data stored at the stock column is lost. I tried to solve this changing the "Action if name is in use" option at the publication. I choose to keep the current object without changes, but I began having problems with the generation of the identity values at the subscriber.

Any suggestions will be welcomed

Thanks in advance ;-)
