Making Donations To a Different Ward

Hi,
Does anyone know if it's possible to make an online donation to another ward? My husband and I visited Hawaii earlier this month and the ward we attended discussed a future youth temple trip that involves a costly airplane ticket. We would love to make a small monthly donation to help with that. I pay our tithing online but I can't figure out how to donate to another ward or if it's even possible.
Thank you!

No, it's not. You can donate to missionary funds in other ward, but that's all. In this case, you're probably talking about a "Other" account - something that's not even accessible to the members of that ward.
