Can I suggest contributions to more than one cause?

You can suggest contributions to more than one charitable fundraiser by going to your Memorial Gifts section. 

Head to your management dashboard.
Click on the Memorial Gifts section.
Choose a new fundraiser by clicking 'Change Suggestion' and select a charitable fundraiser or enter in the name of the first charity you'd like to raise money for. (You can only have multiple charitable fundraisers, you cannot have multiple personal fundraisers.)
To add additional fundraisers, click "Add new charity" button and select another fundraiser.
You can edit your cause's story by scrolling down to the 'Tell Your Story' section.
