How Can I Change A TAG type
Found at:
You can't change a Tag type directly (by editing the existing Tag in the Tag List).
The only way to create a business Tag is to assign a Tag to a Quicken "business". During that process you can choose an existing non-business Tag for the new Quicken business ... and Quicken will change the Tag type to "Business Tag".
To create a new Quicken business and assign it a Tag (or assign a different Tag to an existing business): go to Business > Manage Business Information.
To create a new business, click the Add button; to modify an existing business, select the existing business and click the Edit button.
Once there is a "Business name", you can enter the name of the Tag for that business in its "Business tag" field. If you enter a name in the Business tag field that is not already a Tag, Quicken will create a new tag. If you enter a name in the Business tag field that is currently a non-business Tag, Quicken will convert that tag to a "Business tag" and assign it to the business being Edited.
