Can we use same collection for multiple templates without sharing the data of the attributes?

Summary:

Query on Supplemental Data forms.

Requirement is to use the same Collection for multiple templates without sharing same data of the attributes across the templates.

For this Collection is created by selecting "Share data records among templates/forms" as No.

but, not able to add workflow at the second template created using the same collection

Does this mean all the templates using same collection should have same workflow?

and Do we have to deploy both forms at a time for the workflow to work?

Is there any other way to use same collection across multiple templates?
