We recommend adding another opportunity with a descriptive title and date so that you can tell the two opportunities apart. For example if you have two grants/opportunities for the 3M Foundation you might name one 3M Grant Opportunity - 2016 and the other 3M Grant Opportunity - 2017. This will allow you to add multiple grants/opportunities to a funder without duplicating your efforts.
As you can see in another example below, this is the same grant name for the same organization, but the timing aligns with semesters of school so that the name reflects the specifics.
*TIP:Use the tasks tab to assign custom details and follow-ups for that specific opportunity.
