Reusing Stores

Hello Guys!!

I have the following situation:

One Store linked into one Grid and then, this Grid is linked into four Forms.

The problem:

The Store used in the Grid is apparently instantiated one time and the data changed in one Grid instance are replicated to the others instances.

I need for each Grid instance has its your own instance of the Store.

The Question:

Its possible to Sencha Architect define de Store inside the Grid with something like this:

Code:

store: new App.store.MyStore()

or

Code:

store: Ext.Create(App.store.MyStore)

Then each new Grid instance will have a new instance of the store!

How is the best way doing this with Sencha Architect?

Thanks a lot.
