If you need to make changes outside of SharePoint to a list, you always have the option to use Access. Follow these steps and you will be well on your way to using this feature.
1. Open your SharePoint list
2. Click Actions –> Open with Access
3. A dialog box will pop up on your screen. When it does, click OK.
4. After you click OK, Access 2007 will pop up on your screen. Double click on the list.
5. When the list pops up you can begin to edit. Once finished, do not click the Publish to SharePoint Site button. Simply close Access 2007.
Please remember that Access 2007 is online with SharePoint and any changes you make will reflect instantly. There will be no going back.
Word of warning:
If you need to have more than one workflow for a particular list/library, DO NOT copy a SPD workflow and paste back into the same library.
What happens is that even if you change all of the properties of the files (names, etc.), there is still a hidden property that SharePoint likes to hold on to and uses to identify the workflow. Think of it as an ID.
Basically, you will have two different workflows with the same ID. When you publish one of these to a list/library, everything works fine. When you go to publish the second one, everything seems fine but after close evaluation, you will notice that the first workflow that you published is no longer attached to the list/library.
Moral of the story, don’t be lazy. Create a new workflow even if all of the information is the same.
