Multiple campaign on same donation form

Hi,
I need the option to allow a donor to choose two or more campaign on the same donation form.
This is for a church and we have different departments that can receive donations.
How can I do that?

Or, can I create different Custom Fields and have an amount box next to it, then it will totalize all those amounts and populate the donation amount field?

Hi Victor

Unfortunately, it is not possible. With Joom Donation, users can only donate for a campaign at a time. They also can only enter donation amount into one text file (or choose from list of pre-defined amounts). The system don't have a way to allow him to enter multiple donation amount and then summary all the amounts for the payment
