Is there to have a parameter for an entire list?

Question

Is it possible to have an attribute, like start date, where other columns would use it to calculate their value?

For example the due date column would take the start date and then add the amount of date it takes (which is another column) to it.

I eventually would be referencing other tasks for their due date, but that's for another time.

Maybe you can use another list to store your date in a dummy item. Then read that date from a workflow at creation of the item. Add the number of days you want to the source date and store it in your item.

• Custom List with a date column
• Dummy item with reference date
• SharePoint Designer Workflow on destination list, starts at creation
• Retrieve reference date from configuration list item
• Do calculation on reference date to add days and store it to variable
• Update list item date with variable
