Yamaha PM10 & DSP question

Ive got a show coming up that has 26 Dante devices (8x Shure AD4Q, 8x Rio1608-D2, 8x R08-D2, 2x DVS computer).

The Yamaha website tells me that a HY144-D Dante card in the DSP can only handle 24 devices though, so do I need to add a 2nd HY144-D card? Even though my required Dante count is only about 100 channels each way?

Supplementary question, are the dante networks then separate, if so do I need a computer with Dante controller on both Dante cards, and then won't be able to patch a device on one network to one on the 2nd network?
