Feat Req: Multiple DDNS services at the same time

I’d like to be able to use multiple DDNS services at the same time. Right now, my Peplink 30 only allows me to use one service.

I know there are service aggregators like DNS-O-Matic, but I don’t want to give out my ddns passwords for security reasons.

Can you help implement this? It should be a snap to implement.

Thanks in advance!
